Sony has admitted that an outside party – Anonymous – may have played their part in taken the whole PlayStation Network down, once again.
SCEE said on their latest blog post:
As you are no doubt aware, the current emergency outage is continuing this afternoon and all Sony Online Network services remain unavailable. Our support teams are investigating the cause of the problem, including the possibility of targeted behaviour by an outside party. If the reported Network problems are indeed caused by such acts, we would like to once again thank our customers who have borne the brunt of the attack through interrupted service.
The North American PlayStation Network is down, as well as many other countries.
