Understanding How Facebook Disappeared from the Internet.
I didnโt post about it because I donโt really give a crap what happens to Facebook, but I knew it was a BGP problem in like five minutes. ๐
Really shows how the Hacker News/developer โWhy do we need these infrastructure people, Iโm a networking expert now because I know how to find my IP address at the command line!โ is just utter bullshit. As useful as it is, BGP is difficult to configure and easy to screw up. This was probably just a single line that was wrong in a BGP config and look what happened. (Iโve nearly made this same mistake myself, but at a lesser scale.)
