Can anyone point me to information regarding the global structure of the
Internet in a telecomm/routing sense (this is distinct from the recent
article(s) about the structure of the Web, which has more to do with linking
structures than anything else)? The question I'm trying to ask is
essentially this: what physical places (ISPs/telcos, I'm presuming) that do
co-location for Web servers are going to tend to be the fewest router hops
away from the most end users? Is there a way to evaluate the degree to
which an ISP/co-lo is in the telecomm "core" of the Internet?
The larger issue I'm assessing here is to what extent is it necessary to
deploy servers globally to serve a modest Web function that has a global
reach, assuming that the function in question isn't some kind of
massive-bandwidth thing. If I'm a business in Chattanooga and I'm a
subscriber to a Web service, how bandwidth-intensive a service does it have
to be before it matters whether the Web service's servers are in Atlanta,
London, or Tokyo?
