That's ... annoying.
As an ISP we need to provide a fully functional nameserver for our customers. So, the only way to do that is to run a separate instance of bind9 on another server as an in-house resolver --- or steal someone else' DNS bandwidth to use them as a resolver.
I suppose we can set up ISPConfig with MyDNS on the master ISPC server and run bind9 in slave mode on other servers with zone transfers enabled to have fully functioning nameserver(s) available for our customers.
