From 11 a.m. to 7 p.m. (EST) today, the PlayStation Network will be undergoing maintenance. Both the PS3 and PS Vita versions will be worked on, with PlayStation Store, PlayStation Home, and Account Management being unavailable during this time.
If you still want to play online during this period, you’ll have to have signed-in to PSN over the past few days: otherwise, you may be out of luck.
