try turning off your PS3 system and then unplug your router. Plug your router back in an wiat until you have Internet access again (check against any computers you have in the house). Now turn your PS3 back on and it should sign-in just fine.
I thought it was down because my computers could access the Internet and figured it wasn't my router. After searching the Internet this was the only recent post about it. If it were down there would be a ton like last year. So, try what I said.
Hope it gets worked out for ya.
