Facebook down: Zuckerberg apologises for six-hour outage

Facebook's founder Mark Zuckerberg has apologised for the "disruption" caused after its social media services went down for almost six hours - impacting more than 3.5bn users worldwide.

The billionaire said sorry after an internal technical issue took Facebook, Messenger, Whatsapp and Instagram offline at about 16:00 GMT on Monday.

The scramble to bring it back online eventually succeeded at around 22:00.

But it is likely to increase scrutiny of the social media giant's reach.

For hours, potentially billions of people found themselves without the social media tools they relied upon to keep in touch with friends and family. Others reportedly found they could not access services which required a Facebook login.

Meanwhile, businesses around the world, which use social media to connect with customers, were faced with the prospect of an unexpected financial hit.

Mr Zuckerberg himself was thought to have lost an estimated $6bn (£4.4bn) from his personal fortune at one point as Facebook shares plummeted, according to the business website Fortune's tracking software.

Downdetector, which tracks outages, said some 10.6 million problems were reported around the world - the largest number it had ever recorded.
