These were our symptoms. Labor day weekend we crashed rarely Saturday and that night ran fine, Sunday we were crippled and couldn't even send invites from our server, Monday same crap, it started on the second of sept and seemed to just fix itself around the 6th. I'll check our group page for the exact date. We have ran fine since around that date and as of sometime in the middle of the night early morning today after the update that occurred last night, we have gone down twice. Once very early today and just recently. It was up about 3.5 hours today before the crash we were online for to notice.
I'm going to time again when it goes down. I have to close the server out and relaunch when this occures and resend invites. And it always happens at a bad time for us and our users. Like flying over a volcano bad lol
