The PlayStation Network is doing some spring cleaning on Monday, April 15. The service is going offline between 11AM ET (8AM PT) and 11PM ET in North America. PSN's Euro side is evidently a bit filthier, as it needs a further 3 hours of sprucing; maintenance starts on that side of the ocean at 2PM UK time on April 15, ending at 5AM the day after.

As usual, the PS Store, Home, and account management aren't accessible during the downtime, but online play is as long you've signed in prior to the maintenance beginning.
