Social media sites knocked offline, Lizard Squad hack group claims responsibility

The hacking group Lizard Squad has claimed responsibility for what it said was an attack that briefly knocked several social networking sites, including Facebook and Instagram, offline early Tuesday.

The Facebook glitch was reported in the United States, Asia, Australia, and the U.K. and affected access to the site from personal computers and from Facebook's mobile app. The social media giant's Instagram service was also inaccessible.

Lizard Squad claimed responsibility for the outage in a Twitter posting that listed the sites it said it had affected, which included matchmaking app Tinder, AIM, and HipChat. The message concluded with the hashtagged statements "offline" and "LizardSquad."
