Sigh. The author of this piece doesn't seem to know much. So now
people with clue may well have to spend even more time at IGF, ITU and
the like to explain why this article is flawed. This will be
unfortunate. Some of those people could have spent their time
installing anycast nodes instead of putting out the fire the author's
He/she might as well have whined about why the root servers are
located in places that "disadvantage" people who are not living in or
close to major population centres. And of course there's no
explanation why it could possibly matter if the 3-4 queries a day a
local resolving server makes to a root server take ~50 ms or ~150ms.
Or if someone could tell the difference between the two.
It is of course interesting to note that there are proportionately
fewer root servers in Asia than there are people (or is it IP
addresses?). This does not justify making assertions about a more
"fair and equitable" distribution of root server placement(s).
Whatever that might mean. It will be interesting to see if this
apparent imbalance is corrected by the ICANN plan for dense anycast: https://ripe64.ripe.net/presentations/135-dknight-lroot-dnswg-ripe64.pdf
BTW "fair and equitable" is one of those unfortunate phrases that gets
Internet governance types very excited, not always in a good way: eg
"fair and equitable" distribution of IP addresses.
