Well I didn't have any problems with the random d/c but I just got disconnected for the first time and launchpad won't work. Dang, I was on a roll with kills.
If they were doing bug fixes (rare), they would shut down all servers. No point in applying bug fixes to only one server at a time.
It's no bug I think that a certain ANONfight got a bit mad in game and started C4ing a spawnroom.Then he must have done something to the login server.
