since the http://faf.statuspage.io is either lieing or just not up to date (EDIT: last update was in march...), I post a more accurate version of the points there:
Replay Vault (probably replay server): Partial Outage
-games not ended/replays not uploaded
-replays often corrupted
-replays often desync
-Winners are not shown correctly
-replays of games on higher version of a map not shown
Live Replay Server: Degraded Performance
-players shown in games that already ended
-list of games doesnt correspond to those actually played at the time (several days old, one can see that on games that have a starttime which is in the future)
-friends not colored anymore
IRC Server: Degraded Performance
-color for friendly moderators (why purple )
-upload of avatars malfunctioning
Lobby Server: Major Outage
-many games have individual disconnects between players where 2 players lose connection to each other while staying connected to everyone else (this became less frequent but still happens)
-sometimes games desync when a player leaves
-some players are only able to connect in gamelobby when restarting faf multiple times
-desynced games affect rating
-lobby preset crashes the host (now presets are removed...)
Mod vault: Partial Outage
-Mods cannot be uploaded (only with Downlords client)
Map vault Partial Outage
-maps cannot be uploaded (only with Downlords client)
other problems:
-scores not always reported correctly (even after the latest update)
-game statistics show "data not available" instead of actual stats when the game ended
-hovering acu has a shifted hitbox and cant be hit anymore
-beetles teleporting from transport when split attack is used
-galactic war still not operational
-Coop broken
-Nomads broken
- featured mods don't show up as an activated mod when hosting it (aka normal lobby cant be distinguished from it)
- rating evolution plot missing
-Team matchmaker is currently offline
-Tourney page not correctly working
-Diamond and Vanilla not working
-Murderparty shows score in the same way as usual game where it was supposed to count successful kills
-Tutorial tab not working (links are outdated)
-ACU sometimes able to shoot and build at the same time
if you can think of anything else, just post it in a comment
