I'm not sure I agree with this new post on Karl Auerbach's weblog: "Was ICANN involved in this?  There is no sign of it." I don't see why ICANN should be involved in the manner in which the root server operators deploy their servers. So long as the servers interoperate and coordinate with the master zone file -- and the announced change shouldn't affect those aspects of root server performace at all -- what would ICANN's role be? I don't have Karl's technical background, so I may be missing something, but what?

Later: Karl responds. Thanks!
