I guess the Xbox 360 exclusive was working online servers...

Yeah, I was going to play with a few friends tonight but looks like I'll have to wait (they're out-of-state). Sony was probably attacked again, SCEE has said that earlier this morning. However, they changed their statement to reflect the one released by SCEA saying that it's an emergency outage and it wasn't a hacker attack. Anonymous has also denied involvement.

Maybe a different group? Possibly. In my experience PSN has been utter crap. I chalk it up to bad PSN.
The xbox servers are up, but the games are laggy as hell. I haven't had one game that was normal yet. I don't even wanna play it.
