Proclus on 02 December 2012
Tomorrow, December 3, the PlayStation Network will be inaccessible so that Sony can turn some knobs and flip some switches in the background.
The maintenance period will last from 8AM to 4PM Pacific Time on Monday. You should still be able to play online multiplayer games, but you won't be able to access services like the PlayStation Store and PlayStation Home, or be able to manage your account.
