I am looking for a commercial DNS service that provides
geo-directionality. Suppose I have 4 data centers scattered thruout the
world and want users to hit the closest data center based on proximity
checks (pings, TTLs, latency, load, etc.). I know one can "roll their
own", using various geo-locational data from companies like Maxmind. I am
*not* interested in that. I am *not* interested in applicances like the
Cisco ACE GSS 4400 either (that do this as well):
http://www.cisco.com/en/US/products/hw/contnetw/ps4162/
What I am looking for is a commercial DNS service.
Is the Akamai Edgescape service the closest to what I want:
http://www.akamai.com/html/technology/products/edgescape.html
Is anyone using it? Can you recommend it?
Another service I know about is the Ultradns (now Neustar) Directional DNS:
http://www.neustarultraservices.biz/solutions/directionaldns.html
But this service is based on statically defined IP responses at each of
their 14 sites so there is no proximity checking done.
Thanks,
Hank
