"Disclosure: I work for Infoblox, a vendor who offers a DNS appliance. Even worse, I’m in the marketing department. " At least he's honest. The article basically questions the wisdom of placing an essential service like DNS in the hands of a possible DDOS target/single point of failure mega-provider. Fair enough, I agree actually, I run all my own DNS for exactly that reason. Don't like the chances of selling a DNS "Appliance", though - anyone trusted to be technically competent enough to design the network in the first place should probably know how to set up a server themselves. Configuring BIND (or whatever) is not the hard part really, the hard part is knowing what to configure it with!
