We are currently performing maintenance to upgrade the software for the PlayStation Network from January 17-18th. This maintenance is scheduled to end around 9:00pm PDT (12:00am Eastern) Friday January 18th.
During this maintenance period, you may receive a message that states “Sony Entertainment Network is undergoing maintenance” when attempting to access the PlayStation Network, PlayStation Store, or PlayStation Home.
If you have signed in to PSN within 5 days prior to the start of maintenance (meaning: any time since January 12), you may be able to play games online and enjoy apps such as Netflix, HULU Plus and Music Unlimited during this maintenance period.
Note: During our current maintenance some authenticated users may have lost access. We apologize for this inconvenience and are working hard to restore access as soon as possible.
I can log into PSN finally however, I cannot gain access to MW3 online. I haven't tried any other games yet. I think the only game stable enough to perform a fair test might be BF3 or Gran Turismo 5. FIFA 13, NFS all seem to be inconsistent.
If MW3 is still under maintenance then is there any time-frame we will be looking at? (GMT)
