(very local) root server. Why would that be better for you/us?
if the presumption is low latency name resolution, this might be reasonable, if there was poor/no connectivity
to the rest of the Internet _and_ no caching locally.
The downside of a local root server is that the root server is a global resource and will be expected to field queries
from anywhere on the Internet… Which is why (many years ago) we installed and then removed a root server
from Australia, since they didn’t want to pay for the cost of fielding global DNS queries. Costs have changed since
then, but the basic presumption is still there - a root server is expected to answer DNS priming queries from _ANYWHERE_
on the Internet, not jus those queries local to you.
So please explain why a local copy of the root is better for you? You have cheap bandwidth you wish to donate to the global

> 1. A list of which countries have root servers and which do not is the beginning but not the end of the discussion. The technical question is whether a locale is being served well enough. "Well enough" is usually measured in terms of delay to get an answer to a look up, e.g. 89 milliseconds, and reliability, e.g. answers are received 99.923% of the time. (Both of the numbers in the previous sentence are illustrative and not related to any actual measurement. I made them up as I typed.) On the other hand, many people seem concerned with political questions, e.g. which countries are important enough to have root servers. It would help the discussion to know what questions are being asked. The list of root server locations may or may not be relevant.
