As it is posted on the Playstation Blog, they are pretty much re-building it from the ground up. I assume this will take a while to complete. How are you guys going to handle it? Me? Well, I got dissidia 012 and More trophies hidding in Yakuza 4 for me. Plus Netflix still works on my ps3.

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.
We thank you for your patience to date and ask for a little more while we move towards completion of this project. We will continue to give you updates as they become available.
So check out the PS blog for more news.
