Around 11.45 am on Tuesday, Facebook users around the world started experiencing problems connecting to the popular social media website. "Sorry, something went wrong," said a message. "We're working on it and we'll get it fixed as soon as we can."

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.

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.




 

 



 

Barely an hour after it was down, Facebook was up and running. People again took to Twitter to share this information.
