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.
The PlayStation Network (PSN) has been down (off and on) for the last two days. And it doesn’t look any better for the next two. On the official PlayStation Blog, Patrick Seybold Sr. Director, Corporate Communications & Social Media had this to say:
While we are investigating the cause of the Network outage, we wanted to alert you that it may be a full day or two before we’re able to get the service completely back up and running. Thank you very much for your patience while we work to resolve this matter. Please stay tuned to this space for more details, and we’ll update you again as soon as we can.
In short, they don’t know what the problem is and we’re off on Good Friday so relax… Ok maybe that’s too blunt, but nevertheless you won’t be playing Black Ops tonight or tomorrow. We’ll update this post as we get the info from AskPlayStation’s Twitter page.
