MW2 server failed to communicate on Xbox Live
A bad experience for all the fans of Modern Warfare 2 happened two days before. The game was stopped. The server seized to respond. All the Xbox Live users were not able to figure out how to bring the servers back. For few hours the game was off. There was no communication with the servers of Xbox Live.

The Microsoft technicians tired their level best to fix up the problem for the ongoing Xbox Live outage. They did their best to get over the interruption to the earliest.
The Twitter, the facebook, the digg and every where on internet the news was flooded saying ‘Modern Warfare 2 servers down’, ‘Modern Warfare 2 game not working’, ‘Microsoft Modern Warfare 2 problem’ and many more headlines on newspapers.
Well, whatever be the headlines or whatever be the problem at the Microsoft end, it is not healthy for the best seller of 2009. The developer should take care of all these so that it is not repeated in future.
Hours? You guys were lucky, psn was down for days when mw2 was released
