-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Also keep in mind the trends that the "consumers" of the service use; If ohare got nuked, you would also see a serious DROP off in passengers; much as the airlines are seeing right now. If PAIX fell into the ocean, presumably there would be other things going with it, and there would be an INCREASED usage on the net as people try to scour for information.. Not that that's particularly related to the issue, just another example of why it's a poor analogy..

My point being that building a network which doesn't have more than an annoying route flap, if /both/ 60 Hudson and 111 8th avenue are lost, is extremely hard (*) (especially if it has a transatlantic component). And that's true even if you have your own fiber.
(*) hard means that it isn't compatible with existing topologies, and building new ones is expensive.
Which brings me back to my original question. Are there specific locations which are more important to the functioning of the Internet than others? You can't simply say everything is important. The FAA breaks airports down into several catagories, large airports, medium airports and small airports. A large airport has 1% or more of the passenger traffic. Are there specific locations which handle 1% or more of the Internet's traffic (assuming we had figures for the total amount of traffic).
The national air traffic system makes a poor analogy to the Internet in this case, IMHO. If O'Hare got nuked tomorrow, we'd have some serious disruption in passenger traffic. If PAIX fell into the ocean, OTOH, traffic would simply route around it. Isn't that how we try to engineer the Internet? So in other words, yes, everything is important, and yes, nothing is particularly important. Grant - -- Grant A.
