The bridge drop affected Fedora quite a bit - Fedora traditionally used to have their IRC rooms on freenode, then on libera.chat - including the "official" stuff like Special Interest Group meeting, bug triages, GO/NOGO meeting for release, releng, etc.

While it was decided to migrate to Matrix, still a lot of tooling was built for IRC & many users connected via IRC to the rooms, so the situation with bridges in place was ideal.

But wen the bridge stopped working, it effectively split some of these room in half, with some people being on Matrix and some only on IRC. Worse yet, some meeting still depend on IRC only tooling/bots & happen only on the "IRC side" until the tooling can be ported. Not the best situation. :)
