No I'm with Mark on delegation, I think the problem is their DNS
is housed on and domains, and most of
these servers return TTL of 0 for A records of name servers.
This with BIND 9, and the other delegation issues Mark mentioned
convinced me without doing the details checking of whether there
is one path through the maze of delegation that might actually
cache correctly.

If it was bad recursive servers all domains would break at the
same time.
