There is no point in forwarding just one domain to google recursive servers. 
Either forward ALL domains there (but in such case you could simply avoid
local BIND and point resolv.conf to google), or point the domain directly to
its servers instead of google.

Since BIND 9.8 and you can do it by using "type static-stub" instead of type
forward and use server-addresses instead of forwarders.

If you are trying to say that some of authoritative servers for a domain do
know about one record and others do not know, then the servers and the
domain are broken and they need to be fixed.

So, is that mytestdomain101.com or mycompany.com or mygeo1.mycompany.com?
It would be easier to look at the problem if you provided us correct data.
