Why does psn say "psn is currently undergoing maintenance"?

The same thing is happening to me, and it just so happens that I bought a psn card to buy syphon filter but since maintenance I cant get on psn to download, so im pretty mad too. I googed psn maintence and it said it will open up again at 8:30 pm.

PSN is down for maintenance today. Your probably not gonna be able to play online until later tonight or tomorrow.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
