The commitment to maintain service for 1 year after the new LACNIC addresses are switched in to the root.hints from IANA does not mean that this is a cutoff date and that we intend to turn off service on the older addresses after a year. We currently have no plans to do so for the foreseeable future. In fact, the possibility has not even been suggested or discussed at all.
Such total lack of advance and public discussion and preparation on a substantial change on critical infrastructure is a serious problem, I'm afraid.
I'm curious about what more discussion you want to happen than has happen in the past. Over the last 20 years there have been lots of address changes.
If such changes are performed without proper transition plans even after DNS became critical infrastructure (when?), they also are serious problems.
None of them have caused operational problems.
Thank you for a devil's proof. That you haven't noticed any problem does not mean there actually was no problem. Masataka Ohta
