First InselChaos: Invitation & Call for Participation

Tue, 10 Mar 2026 00:00:00 +0000

The Baltic Sea. Family vacations, nudist beaches, fish sandwiches, sand between your toes and seagulls in the air. For many, it’s a relaxing vacation spot; for us, it’s the best location for the saltiest chaos event in Mecklenburg–Western Pomerania!

After the first InselChaos in 2025 impacted like a seagull on a fish sandwich, we have no choice but to repeat the experience in 2026. Or as visitors would say: “There’s already a postcard waiting for you at C3Post for InselChaos 2026, you have no choice but to come!”

InselChaos 2026 will take place on 4–6 September 2026 at La Grange in Bergen on the beautiful island of Rügen, combining art, hacking, music, and the chaos community. La Grange offers an extraordinary atmosphere for exchanging ideas about technology, society, and creativity, just 20 minutes from the beach on the Baltic Sea. Whether on the stage, in the chill-out area, or in the cozy outdoor space – everyone will find a place and opportunity to express their thoughts and creativity.

Of course, an event like this depends on the Chaos community. In addition to the ticket shop, the Call for Participation is now open. We welcome all kinds of topics and formats, be it lectures, workshops, or whatever else you would like to help to shape. Feel free to write to us – we make (almost) anything possible.

So: Pack your swimming trunks and your favourite microcontrollers and come to InselChaos 2026 on Rügen.

First InselChaos: Invitation & Call for Participation

Tue, 18 Mar 2025 00:00:00 +0000

The Baltic Sea. Family holidays, nudist beaches, fish sandwiches, sand between your toes and seagulls in the air. For many a relaxing holiday destination, for us the best location for the first big chaos event in Mecklenburg-Vorpommern!

The InselChaos will take place on 5–7 September at La Grange in Bergen on the beautiful island of Rügen and combines art, hacking, music and community. La Grange offers the opportunity to exchange ideas on technology, society and creativity in an extraordinary atmosphere, barely 20 minutes from the beach. Whether on the stage, in the chill-out area or in the huge outdoor space – everyone will find a place and opportunity to live out their thoughts and creativity.

Of course, an event like this depends on the Chaos community. In addition to the ticket shop, the Call for Participation is therefore already open. We look forward to all kinds of topics and formats, be it a lecture, workshop or whatever you would like to help organize. Feel free to write to us – we make (almost) everything possible.

So: Pack your swimming trunks and your favourite microcontroller and come to the first InselChaos in Bergen.

rC3: Tickets and Merch now available

Tue, 24 Nov 2020 17:19:34 +0000

This year, CCC hosts the Remote Chaos Experience (rC3).

Ticket sales for rC3 now has started. T-Shirts, Hoodies and Zippers should be ordered until December 6th.

Primarily, rC3 will take place on screens and displays. Various initiatives, hackspaces and living rooms distributed worldwide will create a joint program of streamed talks, online workshops, art and culture. Together, we will experiment with various forms of networked togetherness.

Advance ticket sales

Thanks to the many angels investing their spare time, CCC events are known for their fair ticket prices. For rC3, we do not want to break with this tradition.

The ticket price is 0,00 € + voluntary donation.

But of course rC3 also incurs costs for us. If you would like to support the event, you can either contribute an amount of your choice when buying your ticket, or you can purchase some fancy merchandise.

Click here for the ticket shop.

The good news: There will be no long queue at the merch booth! You can easily order online.

We do not want to impose several weeks of online sales, production, support, debt collection, shipping, returns etc. under hygienic conditions on our volunteer angels. That’s why Tickettoaster takes care of the online store, shipping and everything that goes with it.

We recommend collective orders for data, cost and resource reduction.

Guaranteed availability until December 6th

We take the opportunity to offer a made-to-order advance sale. If you order until December 6th, you are guaranteed to get your desired textile in your size. From December 7th on, chances are it won’t be available much longer.

Order early if you want to wear your shirt in front of the camera at rC3. Logistics and shipping are traditionally at their limits in December. Please be patient if your order does not arrive on time before Christmas. Everybody does their best.

Special: CCC Classics

Beside the brand new rC3-Collection, we also offer shirts with the classic CCC-Logos: Chaosknoten, Pesthörnchen and Tastaturstern.

Of course, there are also shirts for children.

Here you can find the tickettoaster merchandise sale.

Behind the scenes: Chaos Communication Congress presale

Mon, 18 Nov 2019 10:36:16 +0000

A scanner, watching you. Beep!

Have you ever tried to solve a problem that is completely, utterly, ridiculously impossible?

Welcome to our world! We’re the team running the Chaos Communication Congress ticket sales, and we want to follow the good example set by the content teams, and explain a bit of our work.

Now, from the outside, our problems may not seem all that impossible. In fact, you may think we have very little problems indeed: We run the presale of a conference that is notoriously sold out, and that’s generally what you want when you organise an event, right? Well, yes and no. Our primary goal is neither to sell every last ticket nor to increase our prices knowing that we’ll be sold out anyways – our goal is to invite participants in a way that is consistent with the values represented by our event and our community.

The Chaos Communication Congress is first and foremost a community event. Its unique beauty as well as its unique challenges originate in the fact that we are a huge distributed anarchical group of unpaid volunteers who manage to build an event for over 16000 people, every year. To make matters even harder, our completely self-organised decentralised structures work without a single point of authority. If you think that this cannot possibly work, you’re not alone: It’s hard to explain to people on the outside, and when we try, we’re usually met with a blank stare or disbelief.

None of our Congresses would work without two overlapping, vaguely-defined groups of people: The teams who spend inordinate amounts of time before and during the event organising and working, and the local groups and hackerspaces who do a lot of great work throughout the year that has nothing to do with Congress at all. Without the people tinkering in hackerspaces, running smaller events, creating awesome new hacks, educating people, visiting schools to talk to kids, running workshops, discussing positions and organising protests … we wouldn’t have the vibrant community that turns Congress into an event without its like.

Consequently one of our goals is to make sure that both organising teams and active people from other groups have a chance of attending Congress – but at the same time, we don’t want to limit ourselves completely to people who have already done their part. We’d be completely caught in our own filter bubble, and therefore we also want Congress to be accessible to new people.

This is a tough one. Fundamentally, there cannot be a perfect solution: We sell less tickets than people want to buy and our community grows larger every year. Period. Which means that some people will not be able to buy a ticket, no matter how much they want to, or how good a fit they’d be for the event.

Possible solutions to this are manifold: We could turn the event into a private event only for people who are already part of the community. We could just increase our ticket prices until the demand balances with the available tickets. We could go by “seniority” within the community, or by capability by introducing artificial technical barriers (a quiz? a hidden ticket sales server via ssh?). We could insist on a personal recommendation from a trusted person, or expand this into a dystopian voting system where only people with a sufficient number of votes get in. We could set certain quotas by demographics and then distribute tickets according to age, gender, social status, income, text editor, or hair color. We could make ticket sales entirely random (more on that later), or just sell as many tickets as we can, ignoring the problems that start when you let a community grow faster than it can support itself. But we don’t think any of these are a good idea.

Our current solution works like this: We don’t sell all tickets to the general public. Instead, we start by handing vouchers to all dedicated volunteers from last year’s Congress, so they can buy a ticket for this year if they want to. Simultaneously, we also give vouchers to local groups, like hackerspaces, and some activist groups. Their vouchers spawn new ones once they have been used, so that these groups can distribute the vouchers among themselves. Roughly half of our tickets are sold to somebody with a voucher. (The truth is slightly more complex, and if you like reading rule books, you can read up on them in our documentation).

Once the tickets reserved for the active community are used up, we turn to the remaining tickets, and sell those in three open presale days. They are notoriously gone within minutes, if not seconds. The technical challenges of serving several thousand requests per second in an attempt to sell tickets is interesting in its own right, but we’ll leave that ~~as an exercise for the reader~~ for another post.

Obviously, this is not an ideal system and it fails in a variety of interesting ways. For example, local groups may have questionable priorities when distributing their vouchers. People may have broken mailservers and will never receive their voucher. People who use a reproducing voucher may take a long time to pay, blocking people who wait for their replicated voucher. If you have very slow internet or slow reflexes or are not aware of the urgency, buying a ticket in the open presale is nearly impossible. It’s frankly heartbreaking to talk to people who will not be able to attend Congress.

And that’s a significant part of what we do: As the presale team, we answer all emails sent to our address, usually within a day. Last year, we received a total of 2690 emails and sent 1764 in 1623 threads, so roughly 10% of attendees contacted us. This excludes spam, but includes bounces – because we look at those, and try to figure out if there was a typo in the mail address, or if we know somebody who knows this person and can get in touch with them. If you write us, you don’t receive a canned response either – every response is more-or-less lovingly created by one of the four of us.

Other than that, what do we do? We usually deal with requests for vouchers from various groups, which has served to expand our knowledge of geography. Occasionally we help settle local conflicts when one group won’t talk to the other – it’s the Chaos *Communication* Congress, after all. To keep our workload at an unreasonable-but-possible level, we try to send vouchers to only one place per city, region, or thematic community. We also help people who found one of several tempting ways to make errors in their ordering process (typos in email addresses or payment references are the favourite). We help with payment difficulties and supply people with documentation for their visa application. We prepare the on-site ticket checkin – scanning this many tickets is a challenge of its own, of which we have written more here. We also administrate the servers, which is especially challenging when preparing for the open presale days, which can see request spikes of more than 16.000 requests per second, and requires a bit of careful planning. Before the presale starts, we negotiate conditions with the local public transport company, and help determine the ticket prices and what average ticket price we need to reach – you can always see the chart of average ticket prices here.

We’re also constantly looking for ways to improve the presale. Every year we make some minor changes and adjustments that go mostly unnoticed (which is good!). We have experimented with simulating parts of the presale, to get a feeling for the results that we would introduce with different replication rates, spawn times, and distribution mechanisms. This also involves talking to lots of people to help us balance the needs of different groups: Within Germany and from abroad, from within the community and newcomers, marginalised groups and people who have been around for most of CCC’s history, people who cannot participate in a regular presale for health reasons, and so on.

We’re nearly always happy to discuss your ideas, and we only have two requests if you want to let us know what you think: First off, please assume that we’re trying our best – because we are, and people who send us very angry mails about our malice or our incompetence just make us sad, but won’t improve the presale process.

Secondly: Please do not suggest that we try a lottery. We know, it’s tempting – it’s the first solution that springs to mind to solve this problem, but it’s also just not going to happen. The short explanation is: Any lottery that can’t be cheated easily will require us to check people’s IDs at the entrance, and that’s not something we are willing to do – both due to the logistical challenge of slowing down the entire check-in process extremely, and because we follow the principles of minimal data retention. We don’t care about your official names, we don’t want to check your ID, and we run screaming when thinking about the implications of this level of data aggregation.

A last note: While we have seen a lot of bitter, or angry, and occasionally hateful messages, we have also seen plenty of support, humour, and good-natured snark, which makes the whole effort more than worth it. Thank you!

36C3: Tickets & Presale

Sat, 19 Oct 2019 18:20:33 +0000

It’s that time of the year again – we’re opening the presale for this year’s Chaos Communication Congress!

As in the last years, there will be two phases, with the first one starting on 2019-10-21. During the first phase, we will invite the core of our community to participate in the presale. It will end as soon as no more tickets are left in the pool for this phase, but by 2019-11-07 at the latest.

During the second phase we’ll open the presale to everybody on three dates. These dates are:

2019-11-08 12:00 CET
2019-11-10 17:00 CET
2019-11-21 21:00 CET

Usually tickets are gone very fast on these dates, so take care to be on time. We’ll offer all tickets for presale and expect not to be able to sell any tickets on site.

Like last year, the Congress ticket includes a public transport ticket that is valid in all of Leipzig (area 110 of MDV) during 36C3. Again, there will also be more frequent tram and bus connections to and from 36C3, especially at night.

To make 36C3 as awesome as possible, we’ll need to reach an average ticket price of EUR 145. We nevertheless decided to start ticket pricing at EUR 120. Please buy a Supporter ticket if you’re able to, to allow us to continue offering the lower-priced tickets to other attendees! You’ll soon find details and a chart plotting the average ticket price of currently sold tickets at https://tickets.events.ccc.de.

If you are able to support us, please do!

You can find a more detailed explanation of the presale phases and the voucher system at https://tickets.events.ccc.de/36c3/docs. If you have any questions, please refer to the FAQ at https://tickets.events.ccc.de/36c3/page/faq or contact us at mailto:36c3-tickets@cccv.de, if your question is not answered in the FAQ.

If you were logging at least 16 hours in angel shifts last year and agreed to receiving emails from us, you should find a voucher in your mailbox.

Local CCC groups and similar entities have also received their vouchers by now. If you belong to such a group and have not received any vouchers, please check in with other groups in your local and social periphery. If none of them have received any vouchers, please get in touch.

See you in December!

32C3 Ticket Status

Mon, 07 Dec 2015 15:32:37 +0000

As of Saturday morning, the 32c3 ticket presale is sold out. We are overwhelmed by the enormous number of people who want to join us in Hamburg, but unfortunately the venue’s capacity is limited. Therefore, there will not be another batch of tickets for presale.

No more tickets in pre-sale. CC BY-NC 2.0 via flickr/Sascha Ludwig

There will be an also

very limited amount of day passes for sale on-site. Please note that due to the Junghackertag the number of day passes available for sale will be particularly low on day two.

Ticket system re-opens Friday, 2015-07-31, 22:00 CEST

Thu, 30 Jul 2015 19:58:45 +0000

Unpaid tickets ordered before July 16th are dropped now. Do not pay for those anymore!
There will be 250 tickets made available on Friday, 2015-07-31, at 22:00 CEST sharp!
Please pay for your precious ticket immediately after you have ordered it! Ask friends to help you out!
Once those 250 tickets are gone, ~~you can create a verpeiler-friends-request.~~
We all need to move closer together to have enough space for everyone.

Verpeiler-friends-request? If you don’t get your ticket on Friday, you have one very last, very tiny chance: Go to the ticket system and convince us that you are one of our dearest verpeiler-friends. There won’t be many of those tickets available. Also you need to be very patient waiting for a reply. Please try really hard to order your ticket on Friday, 22:00 CEST! We are sold out!

We had a pretty difficult time now: so many messages from so many people wondering if there are any tickets left.

We felt we couldn’t break all those hearts and have managed to increase the number of available tickets a tiny bit. That way we won’t have to turn as many of you away; but this also means we’ll need to share the resources amongst more people – less camping space, less time in the shower, less electricity for everyone at the camp. Please keep this in mind – especially once you arrive – build your tents as close together as possible and consider merging spaces. Sharing is part of the Camp spirit!

Survival tips for professional visitors

Sun, 26 Jul 2015 19:02:52 +0000

We’re delighted by the immense public interest in the diverse activities at Chaos Communication Camp in Mildenberg. All lectures will be remotely available via live-stream and download. This way, we include community members that are unable to attend. Of course, media representatives are welcome as well, as is the team shooting parts of a documentary on site.

However, our Camps have always been relaxed vacations for the hacker community, and we want to keep it that way. We plan to exchange experiences, knowledge, skills; hack and tinker together and (hopefully) expose our potbellies to the sun.

We’re open to press coverage and want to enable journalists to dive into our scene, enjoy off-the-record discussions and – well, just participate. In contrast to the common policy of the public and open Chaos Communication Congress, we ask you to be particularly considerate of our community’s reservations about taking pictures and recording movies – especially in the light of the Camp’s recreational atmosphere. The public area of the Camp is limited to the lecture halls and their stages. Taking pictures and covering lecture contents is no problem at all. Outside of these public spaces, we have to insist that you ask for the explicit consent of everyone in the pictures you plan to take. Please make sure to get this consent before shooting pictures.

Building and operating the infrastructure (power, Internet, sanitary installations, etc.) from scratch is rather costly. Actually, it is really expensive. This is why the Camp costs so much more than our Congress events. Every participant is pulling her weight to make our event happen. Even all volunteers, organizers and speakers pay the considerable entry fee.

That is why we ask all members of the press to pay their share as well, unless they only plan to stay briefly. Since we need to limit press attendees, please apply for press accreditation at our email address presse(at)ccc.de. Please state your date of arrival.

Camp tickets sold out? Not entirely….

Sat, 25 Jul 2015 02:15:13 +0000

– Yes, at this very moment you cannot order any tickets.
– There are unpaid tickets reserved, that we’ll put back into sale.
– We will tell you around 24 hours before.

There is a ten day payment duration. We know you(*), so we usually take this deadline fairly easy. As a campsite has restrictions in space and infrastructure, it is not possible to have more people than space actually available. 4500 Tickets have already gone over the digital cash desk, but we haven’t received the money for all of them.

Now we apparently need to take it less easy: We clean up all our ticket-related issues, like friends and upgrades, before dropping unpaid tickets that passed the due date.

If you have paid more than 4 business days ago, but your ticket is still marked as unpaid, please contact us and provide identifying information about your payment: your IBAN, account holder’s name, payment reference, payment date, etc.

If you ordered your ticket and the due date already passed, you are lost. Go and get a ticket once we put yours back into sale.
SEPA transfers until Sunday might still reach us in time. Non-SEPA international transfers definitively will not! Every payment made after the weekend will neither!
It causes us a lot work if you pay too late, cause we have to bounce your payment manually. Please help each other out with the payment, and distribute this message within your friends&families. Also think about directly pinging usual suspects that you want to see at camp to make sure that they get their ticket!

and ourselves, the usual suspects.
Or: “wir kennen doch unsere Pappenheimer… aeh… Verpeiler!”

On the cost of large-scale projects…

Mon, 13 Jul 2015 23:07:26 +0000

As we all know, the cost of large-scale endeavors is hard to predict. Sometimes, more costs come up unexpectedly. When we started the ticket sale, we presented you with an estimate of the costs at that time. Divide that by the maximum number of participants and you get an average ticket price we had to meet to cover those costs. Those costs were already calculated conservatively, but reality beat us to it (one of the reasons is that we are going to have to produce all the electricity ourselves, another is water).

Thus, the new required average ticket price is up to 228 Euros, instead of 211 Euros. Alas, the current average is below that. That’s a problem, but no worries: The camp will take place, and it will not drive us instantaneous into financial ruin.

We want to give everyone the opportunity to attend the Camp and ask those who can afford a higher price category to actually buy such a ticket. If you already bought your ticket and want to upgrade it, you can do so by writing to camp2015-tickets(at)cccv.de, giving your user name, the desired upgrade, and the transfer reason (e.g. “camp15-abcdef12”).

That way, we can enable people who cannot afford an expensive ticket, but still – like everyone else – want to participate and contribute to an awesome Camp, to do so.

Thank you!

Camp 2015 Ticket Shop is open now!

Mon, 29 Jun 2015 11:27:26 +0000

https://tickets.events.ccc.de/

We all are very much looking forward to Camp 2015 – the new location makes things very exciting but such a new location also makes it very costly: We’ll need to get at least 950.000 EUR from ticket sales, which brings us down to an average ticket price of ~212 EUR.

When we moved the Congress to the new venue in 2012 we have been facing the same issue, remember?
Back then, we didn’t want to raise the price above 100 EUR and right now we don’t want to go above 200 EUR: We leave this, again, up to everyone of you to contribute as much as you can afford to – to make the Camp affordable for everyone in sum.

You can get:

Standard tickets for 220 EUR,
Supporter tickets for 240, 260, 280 and 300 EUR,
Business tickets for 450, 600 and 750 EUR,
Up-and-coming tickets for 50 EUR.
If you are on a low budget, there is the option to buy a ticket for 200 or even 180.
As usual there is also the friends request available, so that everybody is able to attend.

We provide you in the ticket system a graph that shows the average ticket price and how far away we are from the goal of 950.000 EUR. Please help us to create a nice graph! :)

Please be aware that there will be no ticket sale on site! So go ahead and get your ticket right now: https://tickets.events.ccc.de/ – if you have further questions please refer to our wikipage.

Update:
Shame on us, we forgot the Up-and-coming tickets for our young generation! This is fixed now.

If you are under 12 you get in for free! Between the age of 12 and 18 you are eligible for an Up-and-coming ticket for 50 EUR. That means, you must convince us to be born before August 13th 1997. Please bring a (sufficiently convincing fake of a) document / photo ID stating your age.

Chaos Communication Camp 2015: Save the date!

Tue, 10 Feb 2015 16:26:52 +0000

Not just because of tradition, but because we can: There will be a Camp in 2015 again!

After more than three thousand guests at the last Camp in 2011, we expect many outdoor enthusiasts, who like to hack during the day and marvel at the light displays at night and will celebrate the ultimate party in the middle of the festival season with us. Let’s just bring all the great experiences from the Congress out on the lawn and do all the experiments too dangerous for the halls of the CCH!

After an exhaustive search we found the perfect green field site for hackers of all kinds to build a camp with the most distinguished wood illuminators and musicians: the Ziegeleipark Mildenberg (brickyard Mildenberg), located idyllically between waterways, but still easily accessible. Don’t forget your swimming trunks and bikinis, because there is a bathing area right at the site: a truly beautiful swimming lake, just a few minutes walk away and well suited to fight the noble nerd paleness. But if you do not like swimming lakes: We will have the popular shower containers again! :}

Of course, we will put together an exciting talk program, which will be presented in two large tents, accommodating 800 and 1,200 people respectively. Moreover there is a park train system with three different track gauges, winding it’s way through the industrial scenery. There will also be a steam engine and a whole museum on machinery and tools used for brick-making.

Assemble in vacation travel groups! If you are free this summer, August 13th through 17th, we would like to invite you to come to the Chaos Communication Camp in Mildenberg. Where a hundred years ago the bricks were burnt for Berlin, we will set up our Camp. Bring your projects, ideas, space rockets and tents, of course. In return we will provide you with a DIY market near by, three brick bbq places and several bars to care for an appropriate environment to fraternize with others.

Tickets for all four days of the Chaos Communication Camp 2015 will be offered in a presale. The presale will be available in June the earliest. Right now the final price is uncertain, because the calculations are not finished yet. We aim to keep the price for the four day ticket below €200. Of course, people accompanying disabled people enjoy free admission. The Call for Participation for the camp program will be published on this webpage soon.

Save the date for a summer vacation with like-minded people, including working hand rail trollies and locomotives! Until then you might want to indulge yourself in some memories of the Camps in 2011 and 2007.

31C3 Ticket Shop Has Opened

Sun, 23 Nov 2014 22:22:44 +0000

Need to say more?

We’ve opened the 31C3 ticket shop. You can buy tickets online at https://tickets.events.ccc.de/.

You’ll notice we had to raise prices slightly.

It is awfully difficult to predict the total income for an event of this size. Maybe the price for a standard ticket is 10€ too much now, depending on how many people will come. If that turns out to be true, we’ll reduce it again next year.

In the meantime, if you can’t afford to pay the standard price, don’t hesitate to use the “Apply” button on the bottom right of the page. It will present you with a text input and send a mail on your behalf to 31c3-friends@cccv.de. Of course you can send a mail without using that button, too. Rest assured, we’ll find an agreement that makes both sides happy.

Online Ticket Sale is Closing Soon

Sun, 08 Dec 2013 01:04:18 +0000

If you still need a ticket for 30c3, your should order right now!

The ticket shop will not accept any new orders after December 10th, 23:59:59 CET.

We’re doing this in order to grant everybody enough time to make the payment. There will be an on-site sale too, but if you want to speed up the process at the entrance, better buy your ticket online right now. Keep in mind that we only accept cash at the venue!

If you have already paid for your ticket, but it has not been marked as paid on the website within 5 days of your payment, please contact us (be sure to provide some identifying information about your payment).

Credit Card payments now possible

Tue, 03 Dec 2013 03:34:23 +0000

Starting today it is also possible to pay your orders via credit card. Please note that we still prefer wire transfer over credit card payments, and we’ll charge you an extra fee for paying via card. If you do not want to pay the surcharge and absolutely cannot pay via wire transfer, there’s always the possibility to pay cash on site.

In order to pay via card, log on to the ticket shop and find the “pay via credit card” link below the wire transfer instructions.
