I only got a few warnings on that domain name.  For example the
following two queries should return nearly the same info.

$ dig @b.gtld-servers.net dwstudios.net NS

I haven't been tracking it well enough to be sure if this might have
anything to do with it, but there was a major update to DNS in the
last few weeks.  As in every vendor from bind, to Microsoft released a
new version of their DNS server on the same day.
