A lot of people use 8.8.8.8. I don't know whether it is due to the
lemming [1] effect or swarm intelligence.
Now on my corner of the planet Google DNS is 190ms away. Never mind the
mess we have with all the CDNs mapping their traffic to a different
continent.
So what are you thoughts on capturing these queries and answering them
on local resolvers that are <10ms away?
DNS interception is not a good idea in my opinion.
The folks at Google are certainly not going to encourage us to spoof
responses from their servers but are there any other potential pitfalls
with doing this to save the customers from themselves?
Once that becomes popular the regulator might wish to "standardize"
it (see draft-iab-filtering-considerations-02). Saving the customers
from themselves is a good intention.

1. Lemmings are small rodents that have been known to follow each
other as they charge to their deaths off the edge of cliffs. This is
actually an unsubstantiated myth about lemmings.
