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 Krebs explains that the DNS records that tell systems how to find Facebook and Instagram “got withdrawn this morning from the global routing cables.”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.
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, the New York Times reports that even Facebook isn’t entirely sure what the root cause of this issue is:
Several hours into the incident, Facebook’s security experts were still trying to identify the root issue, according to an internal memo and employees briefed on the matter. Two members of its security team, who spoke on the condition of anonymity because they were not authorized to speak publicly, said it was unlikely that a cyberattack had taken place because one hack was unlikely to affect so many apps at once.
In a statement, WhatsApp acknowledges that its service is down:
Facebook’s Andy Stone:
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’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.
The New York Times report says that 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. The Verge reports that Facebook employees have turned to platforms like Discord and FaceTime for communication.
The outage is affecting every Facebook-owned platform, according to data on Downdetector and Twitter. This includes Instagram, Facebook, WhatsApp, and Facebook Messenger. The outages appear to have started around 09:10 pm and all of those services remain inaccessible.
The outages quickly started trending on Twitter as users flocked to the competing social network to check to see if other users were affected by the down time.
