Yeah it is. I asked Rene on Reddit what was going on, there was an issue with Vodafone in Germany and there was some huge blackout. Rene is currently moving servers as well as updating the entire t2 library in a new stable branch for 2022, it should all be done by next week.
For updates visit...
The t2 trunk at svn.exactcode.de where all the packages are downloaded from during the build process is down, or doesn't exist anymore. Does anybody know if it's been changed or what other solution there is?
