Sony has announced that PlayStation Network will be undergoing maintenance on Wednesday, April 22.
Unlike other maintenance periods however, this one will only affect message services; you won’t be able to send, receive, or delete any messages during this time.
The downtime will kick off at 5.00 am and will run until 8.00 pm BST and affects PS4, PS3, and PS Vita platforms.
Fortunately, no other services will be out of action during this time, so you’ll still be able to game online as per usual.
