The latest update of the official PlayStation blog reports that the PSN still offline because they have been working around the clock setting up the system with better security protocols. I think it’s a necessary sacrifice to avoid similar consequences in the future.
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.
