If you plan on doing anything that requires logging into Playstation Network, you have approximately ten minutes (until 11am eastern) to do so, otherwise you will be locked out for thirteen hours until tonight. Sony is conducting routine maintenance on the PSN servers, meaning during this time players will be unable to sign into the service in order to access the Playstation store, account management, and Playstation Home.
This also means being unable to sign into Playstation Network to access your games online. To the best of my understanding, however, if you are signed in before the deadline, you will still be able to play multiplayer games, so make sure you do so in the next seven minutes (I’m going to waste half of that time writing this article). This includes, of course, Free Realms, DC Universe, and Massive Action Game.
Any trophy you receive during the off time will sync when the servers come back up, as normal.
