PlayStation Network wasn’t hacked by Anonymous, if you believe the group, but it sure appears someone hacked Sony’s service. Sony today finally updated its customers again after two full days of downtime (as of this writing). No information on when the network will be up and running was provided, but Sony confessed that an intruder was indeed the problem.

“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,” Sony explained on the PlayStation blog.

“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.”

This is a major blow to PS3 gamers who were looking to settle in with Portal 2 and other online titles over this holiday weekend. It was fairly obvious this wasn’t routine maintenance from the beginning, but now the situation is starting to get out of control. If Sony doesn’t want a PR nightmare on its hands, it’s got to figure out a solution quickly.
