We wanted to take a moment to let everyone know that there is a planned maintenance for PlayStation Network scheduled for Monday, March 4th from
8AM 5AM to 7PM 9PM Pacific Time (11AM to 10PM Midnight Eastern). To clarify, this is an eleven sixteen hour maintenance.
If you’ve signed onto PSN over the past few days, you’ll still be able to play online and access apps during this period, but you may receive a maintenance notification when attempting to access the PlayStation Store, PlayStation Home, and Account Management as these services will be unavailable. Be sure to sign in now if you wish to access the Network during this maintenance window.
Thanks for your patience during this maintenance timeframe, and we apologize for any inconvenience this may cause.
UPDATE: This maintenance will now extend to 9PM Pacific. Thank you for your patience.
UPDATE 2: The maintenance was able to wrap up earlier than expected. All PSN services should be back to normal. Thank you for your patience.
