My point is that’s a manual process.  Some people believe BGP will 
automagically choose the best routes, when in fact it doesn’t know about 
latency, packet loss, etc. without tweaking by a human or robot.

Not required, but typically going along with full routes is access to BGP 
communities. You could fine-tune both what you advertise, what you accept and 
what your upstreams pass along. You don't have to drop the peer entirely if a 
subset of routes is working properly.

So much for the people who believe taking full BGP routes will automatically 
choose the best routes.  (Why does "best routes" sound like something Trump 
would say?)

They're fubar for the last 3 days for different reasons. Today it's a
(another?) fiber cut in LA. Had to pull routes away from Charter to get traffic 
away from Cogent.
