Sony has announced today that the PlayStation Network will be undergoing a scheduled maintenance on December 3, 2012. The scheduled maintenance will be regular one, which means nothing new will be added. The only other detail about the maintenance is that Sony will be toiling away at the PS3's and Vita's network infrastructures.
The scheduled maintenance will be starting on December 3, 2012 at 8 am Pacific Time to 4 pm Pacific Time. For East Coasters that means it will start at 11 am and last until 7 pm. For those of you that want to play online make sure you sign into PSN before the maintenance goes live. Finally while the maintenance is going on you will not be able to access PlayStation Home, PlayStation Store, and Account Management.
