What Happened to Facebook, Instagram, & WhatsApp?:
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.
Doug Madory is director of internet analysis at Kentik, a San Francisco-based network monitoring company. Madory said at approximately 11:39 a.m. ET today (15:39 UTC), someone at Facebook caused an update to be made to the company's Border Gateway Protocol (BGP) records. BGP is a mechanism by which Internet service providers of the world share information about which providers are responsible for routing Internet traffic to which specific groups of Internet addresses.
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.
In addition to stranding billions of users, the Facebook outage also has stranded its employees from communicating with one another using their internal Facebook tools. That's because Facebook's email and tools are all managed in house and via the same domains that are now stranded.
[...] This is a developing story and will likely be updated throughout the day.

That is not a real solution to the certificate problem. You are better off just adding the new root certificate to your trust store and they will all keep working until 2035. You can get the pem or DER from https://letsencrypt.org/certificates/ [letsencrypt.org]
