Also down were Instagram, the popular photo social media website that is owned by Facebook, and Tinder, the dating app that requires users to log in using Facebook.
Shortly after the problems were first noticed , a group of hackers calling themselves The Lizard Squad took to Twitter to claim credit for all the outages. The once-popular Myspace social media platform was also taken down.
Facebook, Instagram, Tinder, AIM, Hipchat #offline #LizardSquad

On Monday, Lizard Squad had taken responsibility for hacking into the Malaysian Airlines website and posting a morbid message, "404-Plane not found".
It isn't clear what provoked this attack. But Whatsapp – the popular messaging app owned by Facebook – was still online, suggesting that the problem did not occur in Menlo Park, where Facebook's headquarters is located.
Since Twitter was the only social media site up and running, that's where users began to complain, and crack jokes about Facebook.
Facebook, Instagram and Tinder are down. Twitter, let us go, we will finally be free.

Barely an hour after it was down, Facebook was up and running. People again took to Twitter to share this information.
Thank God #Facebook is back, the world can continue spinning now.
