Indeed, this is what they do when the agree to put the "national" root

I don't think this stealth business is a very good idea. If you want a
root servers somewhere, use anycast. That means importing BGP problems
into the DNS, which is iffy enough as it is. But for a small network
island just having a single set of resolvers and make sure those have
all the needed information isn't a huge deal. Obviously such a place
doesn't have a huge number of ISPs so the number of DNS servers will be
quite limited in the first place.
I'm a little bit confused here, but I'm starting to get the ideas...
In the Pacific Islands:
http://map.sopac.org/tiki/tiki-map.phtml?mapfile=pacific.map&zoom=1&size=400&Redraw=Redraw&minx=110&miny=-67.6&maxx=230&maxy=52.6&Topography=1&EEZ=1&12+miles+zone=1&Country+Names=1
Countries there have about in general 1000 Internet users, and one ISP
usually some 2 or 3 max...
I think what we need to really solve this is a redesign of the DNS, as
the way it is now it breaks a fundamental design principle of the
internet: when two nodes have reachability, they should be able to
communicate, regardless of what else is (un)reachable. (I'm not
volunteering, though.)
Are we going to something like the Kaza protocol (or peer sharing). The
DNS know their environement and other DNS around and get the ones that
are available to solve ANY query?
I've been in a situation where root servers where unavailable for the
better part of a day, and it's pretty frustrating to see your resolver
cache disappear over tiem so you can no longer reach places to which
you still have connectivity.
