It seems like the servers responsible for login, chat are now pretty stable, but the Game server is (almost?) dead at all times :/ Crash or freeze on every map. Also randomly shows error message with prefix "pg" so I guess this may be some Postgres bottleneck :/
Edit:
[string "bf1/ui/dialogs/pregame/pg_section_browser.|..."]:160:attempt to index a nil value
[1] nil=nil;
[2] string = "[string "bf1/ui/dialogs/pregame/pg_section_browser.|..."]:160:attempt to index a nil value";
