Beginning Sunday, many PlayStation 3 owners found the PlayStation Network inaccessible, with the system giving them an error explaining that they wouldn't be able to connect. This by itself isn't a huge deal, as all online systems crumble from time to time. The bigger problem is that this glitch seems to be affecting the ability to play offline, single-player games, with reports that games like Heavy Rain are no longer functional.

The issue, from reports on various forums, seems to have something to do with the system's internal clock. It also appears that only older, non-slim systems are being compromised, a detail that Sony seems to back up.

"We’re aware that many of you are having difficulty connecting to the PlayStation Network this evening. Those of you with 'slim' PS3s (the 120/250 GB models) appear to be unaffected," the PlayStation Blog reports. "Know that we have narrowed down the issue and have engineers working to restore service even as you read this. We apologize for any inconvenience this may cause you, and genuinely appreciate your patience while we work to resolve this."

The last update was given by Sony 11 hours ago via Twitter, simply restating that slim units have so far been unaffected.

Update: Here's the latest news from Sony. "We hope to resolve this problem within the next 24 hours. In the meantime, if you have a model other than the new slim PS3, we advise that you do not use your PS3 system, as doing so may result in errors in some functionality, such as recording obtained trophies, and not being able to restore certain data."
