A moderator on the official Playstation boards has just posted a message regarding upcoming maintenance and here it is:
“Just a heads up to let you know that there will be PSN maintenance tomorrow morning (30/3/10):
Start time – 03:00 (BST)
End time – 06:00 (BST)
For a period of one hour during this network maintenance, some users will be unable to access PlayStation Network. If you find that you cannot sign-in you should wait one hour after the first failed attempt before trying to sign-in again.”
