Yes I agree with you, however I see it as the more root servers I have in
my region the more local it is to me. US has as many root servers which is
local to them while they worry about the few remaining outbounds.

Yeah! we are both at the same destination through different routes ;)

Definitely cache servers has it's use but we are discussing root servers on
continental basis. Can't we achieve a relatively fair share on the latency
globally ;)

Thanks a lot for having a good discussion as I believe it's been educating
and informative. I think we have bugged the list enough and can take it
further "offlist" (if necessary)

Cheers!

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.
