Of long names...

Thanks.  I appreciate the extra eyes.

I'm pretty sure that GoDaddy has a problem between their WebGUI's database
and their servers.  The records appear in the former, but not (as you
saw), the latter.
Even though their GUI exports the zone file containing them with the
same zone
serial number that your dig's SOA revealed.

After some more detective work, I had a long, unsatisfactory 'webchat'
with GoDaddy
support.  They had all sorts of reasons why they have no problem and
I'm, er, 'wrong'.
Some would be extremely funny if told to a technical audience.

And since there's no problem, they refuse to escalate.  I've made an
out-of-band
attempt to get the attention of their management.

FWIW, bind is quite happy to accept these names in a domain where I run
my own
servers.
