BIND specific workarounds?" is the wrong question becaus even if - the 
domain owner is not in the position to place workarounds somewhere else

Error Missing nameservers reported by parent 	FAIL: The following 
nameservers are listed at your nameservers as nameservers for your 
domain, but are not listed at the parent nameservers (see RFC2181 
5.4.1). You need to make sure that these nameservers are working.If they 
are not working ok, you may have problems!

servers and the NS records point to your own domain, for example).
