I live on the east coast of the USA and my PS3 is currently telling me that the store is unavailable in my country or region and the Uncharted 2 mp demo is telling me that the server is down. I've only had my PS3 for a little over a week so I don't know if this is a common thing or what. Any ideas anybody?

i can't get in either. everytime i try to sign in, it says i got disconnected immediately :(  
i'm also in the east coast.   

They're probably working on it.

No problems here. 
I'm in the EU tho'

I think it's working fine over here in Europe. It was just a while ago.

  East coast here as well, so they must be doing some maintenance  . 

I'm in the Uk, I could sign in but I couldn't access the store, that was around 7pm, it's now 9pm so that might have since changed, it was the same error message though, the region one that is.
