The PlayStation Network will be undergoing maintenance tonight, for a few hours, and will affect online gaming. The network will be offline between 20:30 and 00:00 BST, where all services will be offline. Sony also says that online gaming will be unavailable between 21:00 and 22:00 BST.
Sony didn’t mention if players will be kicked out of their active gaming session between 21:00 and 22:00, but might be worth ending your session just in case.
As usual, Sony say there may also be additional downtime after the maintenance period “for testing purposes”.
