I got into the game with no problems, and stayed in all night.
Unfortunately, Lancer, no one knows. The maintenance was supposed to only run an hour and a half, but it seems there were complications that Sony hasn't deemed fit to mention to us.
Rest assured, though, it shouldn't take too much longer. I am on the East coast (NY State), and it came back for me about 45 minutes ago.
The support page has already switched it back to online, so if you are still not working, Lancer, try turning off your PS3 and turning it back on. That might fix it.
