The delegation for epza.gov.tw from the gov.tw zone specifies a single
nameserver dns.epza.gov.tw (with glue 22.214.171.124). But the server there
thinks that the nameserver for the zone is called ns.epza.gov.tw, and
that dns.epza.gov.tw is a CNAME with target ns.epza.gov.tw.
Using CNAMEs like that doesn't work correctly. Making dns.epza.gov.tw
have a duplicate address record instead would work, but of course what
is really needed is to get the delegation in step with the zone itself.
Having more than one nameserver for the zone wouldn't be a bad idea,
