The fact that the authoritative name servers replied with TCP but not
with UDP, seem to indicate that:
* it was not a layer-3 (or 1 or 2) issue,
* the DNS software was still up.
My guess would be some amateur reviewing the configuration of the
firewall and saying "everybody knows that UDP is dangerous, let's
block it".
