Speculation regarding the cause of the outage has ranged from an Anonymous-related attack to less sinister Amazon server issues, but whatever the reason, it obviously isn't making PS3 owners happy.
While you're waiting, why not buy the Humble Frozenbyte Bundle? Charity and games are cool, right? And if you made a Steam account for Portal 2, it's a great way to use it while you're not playing Portal 2 co-op on your PS3.
