This is gibberish George.  The measurements were taken from different
networks, in 27 different locations.  It is not even potentially the case
that anyone would be measured within their network solely.  It is not
optimized for customers getting to their own web server. 

It is a simulation of the end user world or footprint.  If you have a web
server on one backbone, how will it look to that user population, as
compared to if it were on another backbone.
