We are aware that some users are experiencing error code 8001050F and a network connection failure when signing on to PlayStation Network. Those of you with the newer, “slim” PS3s (120GB/250GB) seem to be unaffected.
We are currently working to restore service as a matter of priority and will update with further information as necessary. We apologise for the inconvenience and appreciate your understanding and continued support.
Keep an eye on our Twitter account, where we’ll be updating you on the situation as often as possible.
