Subject: Re: [IP] Google DNS and OpenDNS vs CDNs

Since the announcement of Google DNS, I've taken it for a spin.

My empirical impression is that it is way slow, slower than Comcast's default DNS service, and slower than OpenDNS, 
both of which are quite speedy.

Even lookups to obviously-cached values such as www.google.com can take ~150 ms,  as opposed to 20-30 ms response times 
from the other two.
