According to a post from All About the Games, there have been multiple reports of XBOX Live issues today. Players trying to play games such as COD, Battlefield 3, and Gears of War 3 on multiplayer have been complaining of disruption to their service.
Microsoft has yet to release an official statement about the problems. So what is going on? Well it could be hackers but then again some guy could have just pressed a button and made things FUBAR. The same thing happened here in California when some dude at an electric company pressed the wrong button, thousands of homes lost electricity and people thought it was a terrorist attack. So just chill people, things will hopefully return to normal soon.
