The switch to anycast for root servers is a good thing.
again there's a tense problem. there was no "switch to" anycast. the last time those thirteen (or eight) ip addresses were each served by a single host in a single location was some time in the early 1990's.
So?
Service by multiple hosts in a single location is hardly anycast.
When it was switched to anycast?
But it was hardly without risks. For example, do we really fully comprehend the dynamics of anycast should there be a large scale disturbance to routing on the order of 9/11?
yes, actually, we do. (or at least the f-root operator does.)
Can you explain, the reactions of people who have been engaging in root server operations against anycast without comprehending the dynamics of anycast, as observed in the last month in IETF DNS OP ML?
