Hello Ray,
I'm not familiar with Akamai's secret sauce. But I suppose geolocation
databases can be outdated very fast over time and things are getting worst
with the ipv4 depletion...
However, if you have a very large number of nodes spread across the globe,
you could use rtt and edns0 client subnet to map users and their locations.
