Re: DNS problems to RoadRunner - tcp vs udp

* Sean Donelan:

Any network with a large user population probably should have separate DNS servers for their authoritative zones answering the Internet at-large and their recursive resolvers serving their user population.

It's not so much a question of network size. You absolutely must use different views if you host DNS for customer domains because there is a race conidtion in the delegation provisioning protocol used by most TLDs (you need to add the domain before you receive the delegation).
