The extension registration for #39C3 is now open!

And because we love good timing, we're dropping another highlight: the “Dawn of ISDN” video is now officially released!

Important note: Permanent Reservations expire on December 24, 2025 – after that they will be automatically returned to the pool.

Have fun registering, and see you soon in the best network!
