(Update) PSN Down For Maintenance
So PSN will be down for 12hrs today, until roughly 8:30pm PDT. If you still be able to log on, but certain things like the store and account management will be inaccessible. For info keep a watch on the PlayStation Twitter account, they will be keeping everyone up-to-date with what is going on.
I am going to spend this down time with some Joe Danger!
Update: We are back!
