I respectfully suggest this is very network-unfriendly.  The amount of
"downtime" is directly related to the length of the DNS cache timeouts,
which means they will probably be set incredibly low - 2 minutes?  10
minutes? It means the servers will be doing much more DNS work than 
usual.  I also find it hard to see how this could handle load-balancing 
adequately, since it looks like DNS lookups are going to return (in your 
case) 129.253.16.1 a lot more frequently than 204.182.160.150, since the 
former is listed as primary for the domain wdc.com.  Could you compare the 
WDC-based traffic loads between the two?

I would say this is the best try yet at trying to make redundancy 
transparant in DNS... but I still think simply having the client test 
latencies of each server would be the most elegant solution.
