Based on recent discussions on the mailop list
the problem seems to be a combination of very short TTLs on the NS records
(which makes any problems occur much more frequently), a weird mapping
from name server names to IP addresses, and lack of EDNS support (which
forces BIND to retry queries).

Bailey: Northeasterly 5 in southeast, otherwise variable 3 or 4. Slight or
moderate. Mainly fair. Good.
