Yikes. This is from the European PlayStation Blog, but it doesn't sound too good...
When we held the press conference in Japan last week, based on what we knew, we expected to have the services online within a week. We were unaware of the extent of the attack on Sony Online Entertainment servers, and we are taking this opportunity to conduct further testing of the incredibly complex system. We know many of you are wanting to play games online, chat with your friends and enjoy all of the services PlayStation Network and Qriocity services have to offer, and trust me when I say we’re doing everything we can to make it happen. We will update you with more information as soon as we have it. We apologize for the delay and inconvenience of this network outage.
Err... The way i'm reading that? "Sorry, but we're not ready yet. Maybe next week."
UPDATE: SCEA has posted the exact same message.
