Facebook: "Internal BGP is awesome, here's a long paper blowing our own trumpet"<p>Also Facebook: "Sorry, we just had a massive global outage when our internal DNS servers withdrew their internal BGP advertisements, it messed the network up so bad we had to send engineers to datacentres to fix it because remote access was FUBAR"<p>Don't get me wrong, I can see the potential benefits of BGP for internal routing, even with all the imperfections of BGP. I just think its a bit funny Facebook is blowing this particular trumpet.
