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 differently. 

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. 

How do I get Server A to resolve to 66.218.71.92?
