Social media services Facebook, WhatsApp, and Instagram are back up and running after an outage that lasted almost six hours, Facebook says.
It blamed an internal technical issue, which not only affected Facebook’s services but reportedly also employees’ work passes and email.
The services were down from about 16:00 GMT until around 22:00 on Monday.
But the company said there was “no evidence that user data was compromised”.
Sheera Frenkel, the New York Times’ technology reporter, told the Today programme part of the reason it took so long to fix was that “the people trying to figure out what this problem was couldn’t even physically get into the building” to work out what had gone wrong.
In a statement, Facebook said that the faulty configuration change affected the company’s internal tools and systems which complicated attempts to resolve the problem.
Downdetector, which tracks outages, said some 10.6 million problem reports around the world. However, the real number of people affected is much higher: more than 3.5 billion people use Facebook, Messenger, Instagram, and Whatsapp.
Many found themselves cut off from family and friends they interact with over the various services, while small businesses which use social media to connect with customers were faced with the prospect of an unexpected financial hit.
According to the business website Fortune, it also cost Facebook founder Mark Zuckerberg an estimated $6bn (£4.4bn) at one point as shares plummeted.
Mr Zuckerberg has apologized to those affected by the outage.
Facebook, Instagram, WhatsApp and Messenger are coming back online now. Sorry for the disruption today — I know how much you rely on our services to stay connected with the people you care about.
