From Verizon in the northeast you have to go all the way to Miami to hit them. I don't think they've quite built out something like the other public DNS resolvers yet... too much latency here from the northeast, and it's not like AS701 is a little "niche" provider.

Second, while it is publicly available for DNS, it is first and foremost a server for Level 3 customers. What they do with it and how available it is outside the network is not guaranteed. YMMV.
