4. Unlikely to be a cyberattack; more likely they hosed their own servers with a bungled update

Looks like they hosed their DNS routing!

Facebook is back online after a six-hour outage due to DNS routing problems. The outage 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 properly on every network.

The outage started just before noon ET on Monday. It was the most significant outage for Facebook since a 2019 incident took its site offline for more than 24 hours.

On Twitter, Facebook communications exec Andy Stone said, “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.”

Inside Facebook, the outage broke internal systems as well, leaving employees unable to get into offices and communicate easily with each other. Some told The Verge they were using work-provided Outlook email accounts, allowing Facebook workers to email each other but unable to send or receive emails from external addresses.
