Eight hours ago, @SonyPlayStation tweeted that they’re aware that most PS users are having problems connecting to the Play Station Network.
The problem was confirmed, and it is being narrowed down to restore the service. It’s still unclear exactly what is really going on.
These problems for PS3 systems include a 8001050F error codes, game crashes, corrupted trophy info, and inability to launch certain titles.
Update1: The “slim” units (120/250 GB models) are already connecting normally according to a tweet from SPS.
Update2: Published on PlayStation Blog, Sony PS3 systems are now up. An update says:
We are aware that the internal clock functionality in the PS3 units other than the slim model, recognized the year 2010 as a leap year. Having the internal clock date change from February 29 to March 1 (both GMT), we have verified that the symptoms are now resolved and that users are able to use their PS3 normally.
