Call of duty Mw3 on ps3 connection to Activision servers lost?

I created a new psn account yesterday to play on Ps3 modern warfare 3. I immediately got into a game, but after a short time I flew out with the indication 'connection to the Activision servers lost'. Since then I haven't been able to get into any game. At the bottom is sometimes the note 'you were in a modded lobby'. Does anyone have experience with it? And before someone comes up with the answer the servers are down: they are not. Many people are still playing mw3.

Ah once your router 10 minutes from the power is an Ip problem!

Ah, had just started again, but that didn't work.

Will be tried tomorrow, thanks! I report.

"Ight"try to restart and resetting the internet network so many time. That still pop out same Problem.
