Battlefield: Bad Company 2 Server Update (2010-03-07) - Battlefield: Bad Company - Battlefield Blog
Yeah, there have been some outages. We experienced one last night that affected our server and also one the night before last (3/6 and 3/5, respectively).
These outages aren't bad and we expect them to eventually be sorted out. Now, with that being said, it is difficult to do anything regarding the game when the master server is down. Last night, I wanted to check my stats so that I could use that downtime to think about what upgrades I had and what I still needed...couldn't do that because almost everything about this game depends on the master server. One thing that I didn't check that I should've was check to see if theses outages affected single player mode (the thinking is that outages with EA or even no internet access should not affect single player mode).
