Umm, then I guess you won't sign a contract with anybody? I sure
wouldn't agree to that. I don't personally write the routing software,
so I can't guarantee there isn't a bug in there (actually, since it is
software, I can guarantee there ARE bugs in there).
We'll see if/when they issue an RFO, but software has bugs, and
configuration errors have entirely unexpected consequences. It's
possible some poor design issue was exposed, or it could be some
basically unforeseeable incident.
Not really the point. BGP is designed such that if I take down the link, the prefixes MUST be withdrawn within reasonable time. The self healing aspect of the internet entirely depends on this. Clearly they have some kind of system that does not respect that by design. I am guessing they have something homebrewn going on with their route reflectors?
It is like a plane. It is impossible to prove or even design a plane that can never fall out of the sky. But now we had a plane that crashed in a very bad way, so that plane (Centurylink) is grounded until they can prove that something like this can not happen again. Which means they need to redesign whatever the hell they have going on here.
