The organization I work for is looking at renewing/upgrading our current internel DNS/DHCP infrastructure, and there has been a divide over a specific question. I would appreciate any feedback.
Should DNS be split to use more than one vendor and product? So DNS would have Server1 be Vendor A, Server2 would be Vendor B, and they would update each other.
One side says yes, so that a single bug/issue doesn't take down DNS.
One side says no, as it adds too much complexity for an isolated chance.
