We (ISC) are widely anycasting f.root-servers.net. Several of the other operators of root nameservers have begun to anycast their servers as well, or announced plans to do so. Is this what you meant? If not, could you elaborate?
Yes this is what I mean
Well just use the LDS index of the UN if you are in doubt, but we are not here in any contest... Outside the G8 is "something". Yes they do need some infrastructure that you may not find in developing country... but then see my last point...> This is a not a very well known fact, and I stumbled upon it recently > after wanting to complain that root servers where only in developed > countries. It's hard to quantify what "developed" means in this context. Our anycast f-root systems, for example, do need some infrastructure around them in order to be useful, but we have anycast clusters in over a dozen locations, most outside of the G8. See f.root-servers.org.
This is not a dangerous half-truth, It has to be demystified. Let's take the example of a country like Tonga. A simple PC will do for them because the number of Internet Users there is may be about a 1000 people. With anycast properly set up only the packet of that country will reach the local root-server (proximity), so it is unlikely to be under heavy load with a 1000 of people on the Internet there...> Oh, btw to install a root server, any PC will do, it is not something > difficult as it carries only a couple of hundred records (200 countries > and a few gTLDs), not the millions of a .com. Operationally, this is a dangerous half-truth. It may be the case that you can run a nameserver that believes it is authoritative for the root zone and will answer for it in this way. But under real world conditions (significant numbers of queries, possibility of DDoS or other attack, etc.) this is far from adequate.
Finally before a root-server is installed somewhere, someone will do an assessment of the local conditions and taylor it adequately. I want countries to request installation of root servers, and I know about 20 Pacific Islands countries that need root-servers in case their Internet link goes dead.
