WhatsApp, Instagram, Facebook face biggest global outage

Facebook, Instagram and WhatsApp became inaccessible for large numbers of people, with Downdetector.com citing reports of problems from millions of users around the world

Facebook experienced one of the worst outages in its history on Monday, leaving users around the world unable to access its platforms, including Instagram and WhatsApp, for several hours.

By late on Monday, the services were slowly coming back online, with the company apologizing for the extended disruption.

To the huge community of people and businesses around the world who depend on us: we’re sorry. We’ve been working hard to restore access to our apps and services and are happy to report they are coming back online now, Facebook tweeted.

In a later blog post, it said faulty configuration changes on its routers were the root cause of the nearly six-hour outage.

Our engineering teams have learned that configuration changes on the backbone routers that coordinate network traffic between our data centres caused issues that interrupted this communication, the statement said. This disruption to network traffic had a cascading effect on the way our data centres communicate, bringing our services to a halt.

Facebook said it had no evidence that user data was compromised.

Facebook, Instagram and WhatsApp became inaccessible for large numbers of people at about 12pm ET, with Downdetector.com citing reports of problems from millions of social media users around the world.

Facebook CEO Mark Zuckerberg, in a post apologising to Facebook users, said that the services are back up and running. I know how much you rely on our services to stay connected with the people you care about, Zuckerberg said in a Facebook post.

The Facebook outage has become the largest outage we’ve ever seen on Downdetector with over 10.6 million outage reports all over the globe, Downdetector said in a post. The maximum number of outages were reported in the United States with over 1.7 million outage reports, followed by Germany at 1.3 million outage reports and the Netherlands at 915,000 outage reports. The outage left all services under Facebook’s umbrella including WhatsApp, Instagram, Facebook Messenger, and even Oculus non-functional for several hours.

The outage affected potentially tens of millions of users, organizations and businesses, highlighting the widespread global dependency on Facebook and its platforms. Countless websites and applications use Facebook’s advertising network, one of the largest in the world, meaning effects from the outage extended far beyond the platform’s users, Luke Deryckx, the chief technology officer for Ookla, wrote in the Downdetector blogpost.
