I think I must have been referring to the server using its name, which 
caused dig to use IPv6. I also see timeouts on IPv4. Full dig output 
included this time, to satisfy Warren's great thirst for cut and paste.

Just goes to show, IPv6 is better. :-)

These are Neustar-hosted zones. Surely there are still Neustar people on 
this list who can say "thanks for letting us know, a fix for v4 is in 
the works".
