Facebook, WhatsApp and Instagram are back

Facebook, Instagram, Whatsapp, and Facebook Messenger were down for several hours due to Domain Name System (DNS) issues. Brian Krebs, one of the internet researchers confirmed that it is a DNS issue in a tweet saying:

“To be more precise (and Geek Factor 5) the BGP routes serving Facebook’s authoritative DNS were withdrawn, rendering all Facebook domains inaccessible.

The DNS records that tell systems how to find these websites got withdrawn this morning from the global routing tables. DNS records search came empty for these services.

According to ARSTECHNICA, the problem goes deeper than Facebook’s obvious DNS failures, though. Facebook-owned Instagram was also down, and its DNS services—which are hosted on Amazon rather than being internal to Facebook’s own network—were functional. Instagram and WhatsApp were reachable but showed HTTP 503 failures (no server is available for the request) instead, an indication that while DNS worked and the services’ load balancers were reachable, the application servers that should be feeding the load balancers were not.
