nameserver, and got no response, that might explain the lame delegation
warnings, regardless of whether a EDNS0 query via UDP works or not.
Yet your point here explains my initial response: there are times when solving
a symptom is still useful, but it's generally more helpful to solve the root
cause. Oh, it might not be the case that fixing ns3 and making sure that all
of the nameservers work over both TCP and UDP port 53 will resolve the lame
delegation messages, but I'd start with fixing things which are obviously
broken first, and then recheck whether than fixes the delegation warning as
