Sony’s confirmed it will be pulling PlayStation Network offline in the U.K. later this evening for maintenance.
The platform holder said the service will be offline from 5PM – 6PM BST, though noted it may be down for a while longer due to “testing purposes.”
This essentially means that all PSN services, including the PlayStation Store, PlayStation Home, and account management, will be unavailable during this time.
However, as always, if you sign in prior to the downtime you should be fine to continue gaming online during the outage.
