Facebook is back after a six-hour outage

Facebook is back online after a six-hour outage due to DNS routing problems. The interruption took down Instagram, Whatsapp, Messenger, and Oculus VR as well.

For some, those services are back online now; however, after a DNS issue like this, it could take hours for everything to work correctly on every network.

"We're aware that some people are having trouble accessing our apps and products. We're working to get things back to normal as quickly as possible, and we apologize for any inconvenience," Facebook tweeted about six hours ago.

As of roughly 3:30 p.m. PT/6:30 p.m. ET, Facebook services were slowly coming back online, the social network said.  "To the huge community of people and businesses around the world who depend on us: we're sorry," the company tweeted. "We've been working hard to restore access to our apps and services and are happy to report they are coming back online now. Thank you for bearing with us."
