You should check the zone files to ensure your glue records are present,
and that the zone is loading properly. If you run your own name server
you typically can grep for named in the syslog, and look for errors, but
I don't think you'll be able to do that here.
I would verify with your hosting company that those really are the
correct name servers, and have them verify the zone records. It's
possible to make entries that really piss the name servers off, even if
you're using one of their automated tools.
I went through some of this pain last week, because I was using a
secondary that was checking the wrong source.
