Episode description
A Border Gateway Protocol (BGP) misconfiguration is what took out Facebook on 4 October. Most IT folks don't understand how BGP works. This episode helps you gain a better understanding of the protocol that creates routing tables to move information from one end of the Internet to the other. We'll explain how Autonomous Systems (AS) share BGP route information, what should happen when things go right, and then examine what likely went wrong at Facebook and how you might be able to prepare for potential problems in advance before they occur.
