After doing more than my share of server upgrades (thankfully all mine have gone smoothly), and "cleaning up" several that didn't go so well, I'm just thrilled to see the game back at all. I start sweating whenever I see "server upgrade" listed anywhere. We are all lucky they were only a few hours late.
I once saw a server move go bad for a few days because no one could figure out that the server was physically moved next to a wall with an elevator on the other side. The server crashed whenever the elevator went to that floor.
Good job guys, I know how hard it can be.
