Even though 40C3 is moving a few doors down the road, our ticket presale will work pretty much the same as last year: We’ll again be using our system of replicating vouchers. The presale will run in two phases: the voucher phase and the open sale. We’ll explain this as briefly as we can here. If you want to read more about it, we also have a documentation page available, where we’ll add more information in the coming days. The voucher phase will run from 2026-10-23 10:00 (CEST) until 2026-11-10 23:00 (CET) and works as follows: There is a fixed quota for this phase.
