Comment (by anarcat):

 i also "renumbered" ns2, ie. i pointed it at ns3's IP addresses, with a
 note in the zone file about the decision. i picked ns3 because it seems to
 be the least busy of the nameservers according to Grafana.

 the rationale behind keeping a ns2.torproject.org record is that we might
 still have some glue records (unlikely) or zones (very likely, onion-
 router.net is one) pointing to it. even though we want to retire the
 machine, we might not want to deal with changes in that other zone,
 especially since we might switch DNS services anyways in the long term.

 so this will be ready for decommissionning, which i'll finalize tomorrow.
