Doug Madory, director of internet analysis at the network monitoring company Kentik, said someone at Facebook caused an update to be made to the company’s BGP records, which resulted in the company’s system taking away the map telling the world’s computers how to find its various online properties.
Now, when someone types Facebook.com into a web browser, the browser has no idea where to find the website, and therefore displays an error page.
In addition to preventing its billions of users from utilizing the social media platform, the Facebook outage has also prohibited the company’s employees from communicating with each another using their internal tools, as Facebook’s email and tools are all managed in house, via the same domains that are now offline.
Not only are Facebook's services and apps down for the public, its internal tools and communications platforms, including Workplace, are out as well. No one can do any work. Several people I've talked to said this is the equivalent of a "snow day" at the company.

Was just on phone with someone who works for FB who described employees unable to enter buildings this morning to begin to evaluate extent of outage because their badges weren’t working to access doors.
