Yahoo uses akamai technology (bgp path analysis) to determine what =
content server is "closest" to a given host and bases its' dns response =
on that data. You could contact Akamai and, explain your network, and =
see if they can make the necessary adjustments, or if you are large =
enough ask them to drop a couple of servers in your site. (or they may =
want you to send them a BGP feed)

Subject: DNS resolution to Yahoo.
So I got 2 dns servers that resolve www.yahoo.com =
<http://www.yahoo.com/> differently. =20
Server A goes to 216.109.125.69. The Server B goes to 66.218.71.92. =
The 66.218.71.92 is a faster route for me. =20
How do I get Server A to resolve to 66.218.71.92?
