Sorry our crystal balls are broken.  Why can't anyone report the
actual domain name they are having problems with?  "A subdomain of" is *not* reporting the actual domain name.  If you
want help from people stop making them guess where the problem
is. had mismatching NS RRsets at the delegation but that
shouldn't cause resolution issues.
