My answer, in short, was to say that I see it as more of an enterprise

If you are an ISP, you are theoretically multi homed by definition
and your providers are going to remain fairly stable (you hope)
based on your own needs.

My point remains: designs based on such assumptions are not a good idea, since these assumptions are by no means fundamental and could certainly change. People get creative with how they announce prefixes, change upstreams, etc., and you can't assume that things like this would stay the way they are.


Nick:

I wouldn't call them assumptions. I would call them engineering decisions in operational environments. I guess I fail to see where a commodity market with a broker adding a vig resolves a real network problem. I'm think tier1? They aren't buying service from anyone on Equinix direct and move/add/drop is just another day on the Internet. I really can't see any provider doing it, but perhaps smaller ones. *shrug*. I don't know why you wouldn't make temporary arrangements via peering fabric, PNI, or transit and eliminate the middle
man (point of failure).



As an aside, another question occurred to me about delaying unusual announcements. Boeing Connexion offers another example of unorthodox prefix announcements. Wouldn't the tactic of delaying unusual announcements would cause problems for this service?
