BIND does it but what about Microsoft cache/forwarder? At RIPE 45 (you were there),
Was I???
a talk by people at CAIDA showed that A.root-servers.net received twice as much traffic as the other root name servers since it is just the first one listed...
That's not good. But not an excuse. If MS is unable to fix this (how long did it take them to retire the FAT filesystem that was considered prehistoric by the late 1980s again?), BIND runs under Windows too...
(but I hope they're smart enough to keep some non-anycasted root servers around),
Who is "they"?
Not sure. :-)
Since there is no top Root Nameservers Authority, every root nameserver manager decides for himself (I assume they coordinate but I'm not sure and it's not the same thing). Unlike a TLD, there is no central decision for management of the root's name servers. So they can all decide independently to anycast.
Diversity is a good thing. But who to the root operators answer to anyway? Not to ICANN, I'm told.
