Hi David,
I think what they're doing is setting up proxy servers to be
the publically listed web servers, where those proxies in turn
forward the web requests and traffic to and from the real
servers, thus providing some protection against attack.

Am I reading this correctly?

I'm wondering if doing the same with DNS traffic would be
possible or advisable as a way to protect the name servers.
On the other hand if the proxies get DOSsed off the Internet,
I'm not sure how much they would be helping at that point...
