Running a dedicated server I have noticed it doesn't Auto reconnect to Matchmaker when "Pause While Zero Players="1" is set" . With "Pause While Zero Players="1" set in the multiplayer.ini the server pauses in practice when there is nobody on it. Since it seems the server only connects to matchmaker when the track is loaded it remains offline as it is paused. So all servers running with this option they will stay off-line when they loose their connecting until they are manually restarted. Server with this option not enabled will only reconnect after all sessions (practice/qual/warmup) are finished. This isn't great either as they can remain offline for a long time when long sessions are used. Better is to have a auto reconnect after a random time, so not all server will try to reconnect at the same time when the matchmaker goes offline .
