While some Facebook, Instagram, and WhatsApp outages only affect certain geographic regions, the services are down worldwide today. This includes the United States, the UK, Brazil, Kuwait, and more.
The outage is also affecting platforms and services that use Facebook login. Niantic, creator of Pokémon GO, says that it is “looking into reports of errors associated with Facebook login, and will update here once we have more information.” Other services that also use Facebook login are believed to be affected, as well as Oculus.
Cybercrime reporter Brian Krebs attributes it to a major DNS problem. Krebs explains that the DNS records that tell systems how to find Facebook and Instagram “got withdrawn this morning from the global routing cables.” At this point, however, it’s unclear how this happened.
Krebs writes in a blog post:
Facebook and its sister properties Instagram and WhatsApp are suffering from ongoing, global outages. We don’t yet know why this happened, but the how is clear: Earlier this morning, something inside Facebook caused the company to revoke key digital records that tell computers and other Internet-enabled devices how to find these destinations online.
In simpler terms, sometime this morning Facebook took away the map telling the world’s computers how to find its various online properties. As a result, when one types Facebook.com into a web browser, the browser has no idea where to find Facebook.com, and so returns an error page.
Meanwhile, reports reaching us is that even Facebook isn’t entirely sure what the root cause of this issue is.
Facebook’s internal Workplace site and associated services for employees are also suffering from an outage today, according to Jane Manchun Wong. The company has distributed a memo to employees about the issues. Employees are referring to this as a “snow day,” including Instagram CEO Adam Mosseri.
Virtually everything inside Facebook is broken, including the ability to use keycards for entering buildings, security systems, an internal calendar and scheduling tools, and more. Facebook employees have turned to platforms like Discord and FaceTime for communication.
