Re: Looking for verification that Google and Akamai have the geo-ipfor 96.31.0.0/20 set correctly

Funny this should come up...

I've found that a local Mobile Broadband outfit here in NZ are using an IP 
range that Akamai's Geolocation service thinks is actually in New Jersey. 
Causes me some oddness as a result - this despite the fact that Maxmind 
has it correct.
Whilst investigating this (just the day before yesterday) the following 
URL came to my attention - allows you to check the IP you're on against 
Akamai's Edgescape product:

http://www.akamai.com/html/technology/products/personalization.html

Their customer care team were responsive to an email I sent them (but were 
unwilling to make changes without the request coming through their 
customer... which in itself seems mad, their info is wrong - why don't 
they correct it?)

Geolocation is clever, but seems to be  very retrospective, and very much 
an imperfect science... there should be some obligation on people offering 
the service to work very hard to keep their data current, given the effect 
it can have on an end user.
