Oh, that's brilliant.  How nice of them to defeat the concept of redundancy
by limiting me to only two of their servers for a gTLD.

VeriSign might be doing some loathsome things lately, but at least my named
has several more servers than just two to choose from.

I tracerouted to both IPs from two different locations in the USA; both took
the same route before hitting !H from an ultradns.com rDNS machine.  And
both servers for that route were completely unresponsive from both tried
locations during the outage period.
