BGP is how routing information is passed around on the internet.

Just before Facebook dropped offline, a bunch of Facebook-related BGP 
updates propagated, and the updates effectively expunged Facebook from 
the Internet.

The whole of the Facebook IP address space—including their DNS servers, 
their web servers, their Facebook status server, and everything else 
Facebook—are presently inaccessible.

DNS translation requests can't get to the Facebook DNS servers to get a 
DNS translation for any of the Facebook servers or services, as there's 
no route to the Facebook DNS servers.

Widespread internal Facebook network service outages are also being reported.
