Sony announced that the Playstation Network will be down for maintenance on Monday.
Announced via the Playstation Blog, the scheduled maintenance will begin at 4pm (9am PDT, 12pm EDT) until 6:30pm GMT on Monday 23rd March.
As usual, on your PS4 if you have logged into your account before the scheduled maintenance and you have activated it as your primary console, you will still have access to online gameplay. The same goes for PS3 and Vita owners who log in before the scheduled maintenance.
“PS4 users will be able to access online gameplay only if their system is activated as their Primary system and they have recently signed into their SEN account and have their authentication details cached.
If your PS4 system is not activated as the Primary system, online gaming may not be available.
PS3 and PS Vita users may experience limited PSN functionality, however online gameplay will be available to users who have recently signed into their SEN account and have their authentication details cached.”
