Lets bring this discussion to a some common ground -
What kind of implact on the global internet would we see should we observe nearly simultaneous detonation of 500 kilogramms of high explosives at N of the major known interconnect facilities?
N? Well, if you define N as the number of interconnect facilities, such as all the Equinix sites
Lets say that N is 4 and they are all in the US, for the sake of the discussion.
(and I'm not banging on Equinix, it's just where we started all this) then I think globally, it wouldn't make that much difference. People in Tokyo would still be able to reach the globe and both coasts of the US.
This presumes that the networks peer with the same AS numbers everywhere in the world, which I dont think they do. The other thing to think about is that the physical transport will be affected as well. Wavelenth customers will lose their paths. Circuit customers that rely on some equipment located at the affected sites, losing their circuits. Alex
