The PlayStation Network will be going offline later today for scheduled maintenance. The network will be down from 2:00 PM BST today, until 5:00 AM BST on Tuesday morning, which means you can say goodbye to any online gaming today evening. If you want to continue to play online, you’ll have to sign-in to the PlayStation Network before the downtime begins.
During the maintenance window, any PSN features will be unavailable, including the PlayStation Store, Account Registration / Management sections and the sonyentertainmentnetwork.com website. Users who are signed into the account prior to the start of the maintenance should be able to stay connected and will not lose their online session for gaming.
