The PlayStation Network maintenance that was schedules to take place on Monday has been rescheduled for later today, Sony has announced. The maintenance will start from 16:00 BST today, and last until 05:00 BST tomorrow morning, effectively ruining your evening gaming session. It also appears that the original maintenance period has been extended, most likely as a result the DDoS attack on Sunday.
If you wish to play online during the maintenance window, be sure to sign-in before the start of it. All PlayStation Network services will be unavailable during the maintenance window, which includes the PlayStation Store, Account Management services and PlayStation Home.
