        dare i say "duh",

        but ...

        ultradns uses the power of anycast to have these ips that appear
to be on close subnets in geographyically diverse locations.

        go to europe, traceroute to them, it goes to a place
in europe.

        go to asia, traceroute to them, it goes to a machine in
asia.

        in the us, it goes to one of a few geographical locations ...

        could you provide some more technical details, other than
your postulations that they have two machines on
network-wise close subnets and that is the problem?
