Comcast doesn't give me broken name servers to use, there is no cognitive dissonance here :-)

You are a DNS expert. Most end users when DNS fails think everything has failed, including the network.

I type URLs into my browser. Do you know how many people type google into the google search box? Or the yahoo box?

You seem disconnected from the average user and average user tech support.

Even small networks (I have a friend with a ~100 user wisp) shouldn't run their own caches. The economics of it don't support this.
