Is it possible to run ENTIRE site (not just images, etc) via CDN?

I know the DNS looks bad, but I think you have to remember that the test location in the AU is inside a Hosting provider network. The information about the CDN-nameservers isn't generally cached, that would be different on a access provider network.

The Edgecast nameservers have a TTL of 2 days, the CNAME has a TTL of 1 hour.

If you do 2 tests, with a little over an hour between them, you should see a more realistic view of what a user on an access provider network would see.
