I probably don't agree that it is not a reliable way to draw conclusions
about backbone performance.  The index has drawn criticism because it
points up winners and losers and that's about it.  There is no way to do
this without criticism, and indeed it should be part of the process.

The end user experience will reflect the sum of that, plus dialup variables
which we simply do not include in this work.

Jack,

I think you've stated for yourself the reason that this Index has 
drawn some criticism.  

By it's name it purports to be an index of backbone speed or backbone 
congestion or a combination of the above.

Not only is it not really an index of these items, it could further 
be argued that there's not even any reliable way to draw conclusions 
about backbone performance from the Keynote measurements.  As you 
say, there are many other variables.  So why not give this thing a 
name that reflects it's real identity as an end-to-end test from the 
Keynote Perspective Agent locations to various WWW servers.

This assumes that you consider web server location and web server
performance to NOT be a part of overall network performance.  Our view
steps back a bit from that.  The majority of traffic would appear to be
webcentric.  From an end users perspective, what does a web site on a
specific network look like and how does that compare to a web site on
another network?  There are ENDLESS variables contributing to that
including intercity links, hub architecture, host hardware, host
software,
peering, connectivity points with other networks, transit agreements,
type
of routers, ATM switching (or not).  All contribute.  We think most
people
notice Internet performance (or lack thereof) while viewing world wide
web
pages.
