PlayStation 3 systems across the globe have been struck with the 8001050F error.
On February 28, the calendar on original PS3 systems was reset to January 1, 2000, blocking access to online content. It has been confirmed that Slim PS3 systems have not been affected.
The console will fail to access PSN, load games with Trophies or play PS3 Originals or Premium Themes. Users have reported that Trophy data has also been wiped.
The error has been identified to strike offline systems, suggesting a firmware error related to a leap year miscalculation.
Sony has told Twitter followers: "We're aware that many of you are having problems connecting to PSN, and yes, we're looking into it. Stay tuned for updates."
It has been advised that users with older PS3 models should not use their console until further notice.
