If you experience some PlayStation Network funkyness today, know that Sony’s messing around in the backend yet again. Starting at 16:00 BST today — which is right about now — until 23:00, PSN may behave somewhat oddly for a few (via). Nothing major, but “a small number of users may be affected when making PS Store purchases or downloading content.”
“If this does happen simply re-attempt the action and it should succeed,” it’s recommended.
Next Wednesday will be a bit more serious with the PS Store, account management and account registrations affected from 16.00 until 00.00. PS Home will be down as well.
As usual, if you’re signed in before the maintenance begins, you should be good for online play.
