PSN Offline Due to 'External Intrusion [Update]

Update 2: Patrick Seybold posted an update on the PlayStation Blog tonight saying the outage will continue and that Sony is re-building its system to "further strengthen our network infrastructure." His statement can be read in full below: 

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.

Update 1: Sony tonight issued a statement saying the PlayStation Network outage is due to an "external intrusion" but did not clarify beyond that. A timetable for when PSN will be up and running again was also not provided. 

Hacker group Anonymous said today they are not claiming responsibility for this particular outage, however. 

The statement in full from Senior Director of Corporate Communications Patrick Seybold can be read below: 

An external intrusion on our system has affected our PlayStation Network and Qriocity services. In order to conduct a thorough investigation and to verify the smooth and secure operation of our network services going forward, we turned off PlayStation Network & Qriocity services on the evening of Wednesday, April 20th.

Providing quality entertainment services to our customers and partners is our utmost priority. We are doing all we can to resolve this situation quickly, and we once again thank you for your patience. We will continue to update you promptly as we have additional information to share.

Original Story: PlayStation Network outages may last up to a full day or two before the service is back up and running, Sony said today. 

The company is currently investigating the cause of the outages, which began late last night. No word yet on whether or not this outage is related to the same outage occurrences from earlier this month that was likely spurred on by the hacker group known as Anonymous.
