Sony’s PlayStation Network has been down since Wednesday and the outage was due to their network being hacked. No words from Sony when the service will be up.
From Playstation Blog:
We sincerely regret that PlayStation Network and Qriocity services have been suspended, and we are working around the clock to bring them both back online. Our efforts to resolve this matter involve re-building our system to further strengthen our network infrastructure. Though this task is time-consuming, we decided it was worth the time necessary to provide the system with additional security.
