Hi George,

Actually the idea of NHE is inspired partially by CDN stuff, which involve
lots of measurments
and route users to visit a best path against network dynamics.  It proves
to be a good practice
for morden Internet. No doubt. I'm wondering CDN is also breaking DNSSEC to
stub-resolver, right?
