How is knowing the physical location going to decrease page load times?

Hint:  I live all of 3 miles from my office.  But home is deep in Comcast
cable territory, while office is hanging off connections to Ashburn and
Atlanta. So from home to office, packets have to go 400 miles north or south,
then back.  If Akamai decided to serve me a page at home out of the Akamai
servers at work because it's only 3 miles away, it just added 25ms to each
RTT it has to take.

Which is why Akamai (and any other *sane* CDN) make their decisions based
on network topology, not physical location....
