The issue is specific to his domain, since I use Savvis for my backbone, I
thought it best to check, and everything is fine for my block 209.144.1.0/24
in both servers.

Good catch.

The problem here is that savvis.net's DNS servers are broken.  One of them
(ns1.savvis.net) is correctly returning the a reference to the
microneil.com DNS servers, the other (ns2.savvis.net) isn't.  Since both of
them are claiming to be using the same zone for 88.216.in-addr.arpa., but
are returning different results, they are broken.
