Playstation Network Help

Everytime I turn on my Playstation 3 today, I keep on getting the error 8002A402. Yesterday my Playstation Network was working fine. Any ideas will be appreciated..

PS. I searched Google with no luck..

Found an answer, can the mods please close this thread.

You can close by clicking on the "Thread Tools" and choosing "Close Thread"

Just for future reference ;)

It means that PSN is under maintainance, so dont worry! :D
