What is going on with the Playstation Network?

I just got my PS3 back since January of this year. I know the network was down but now i can't login at all. The site from the computer tells me i need to login and change my password on my PS3 because the site online is "down for maintenance" But it wont let me login my PS3 either :( i even tried to create a new account. I can't even do that. I need help!
