If you are a PlayStation 3 gamer, you will be disappointed to know that you will not be able to log in to the PlayStation Network for 13 hours today. Sony said that this is necessary maintenance on the network. They are going to optimize things and clean up. The network will go offline at 9AM Eastern time and it will last for about 13 hours. ?During much of this time, users won?t be able to access the PlayStation Store, PlayStation Home, Account Management or play online. PSN enabled websites will not be able to service users, including [the PlayStation Blog],” stated PlayStation Digital Platforms senior manager Matthew Harper.
