Izumi Okutani and CRISP’s 24-hour objection window

Izumi Okutani Gave the IANA Draft a 24-Hour Doorbell

Why it matters

The number community’s 2015 IANA proposal came from a 15-person team. Its most revealing design feature was a day left open after the meeting ended.

Summary

Izumi Okutani chaired the CRISP team from its first teleconference on 9 December 2014; its 15 members were drawn from all five RIR regions.
Decisions made on calls were published with 24 hours for those absent to comment. The final 15 January 2015 proposal paired that drafting discipline with a service contract and review body.

A meeting can end with the chair saying everyone agrees. That is a dangerous sentence when five regions are in the room and half the world is asleep. Izumi Okutani chaired the team drafting the Internet number community’s answer to the IANA stewardship transition. Its useful invention was small: after a decision on a call, leave the doorbell working for another 24 hours.

APNIC’s November 2014 appointment notice named Okutani and Dr Govind as Asia-Pacific community representatives. Craig Ng joined as APNIC staff support without a vote. The team’s January 2015 proposal records three people from each of five RIR regions. At its first call on 9 December, the group selected Okutani as chair and Alan Barrett as vice-chair. Calls were open to listeners; a public mailing list carried discussion and archives. Even the members-only sending list left a public archive.

The proposal describes the 24-hour window precisely: a call decision went to the team list, and people who missed the call could comment before silence was counted as consensus. Two public drafts invited wider response before the 15 January submission. Okutani later introduced an APNIC explanation as CRISP chair, pointing readers back to the actual proposal. The clock was a team rule, recorded for outsiders to inspect, and Okutani chaired the process that used it.

What was at stake justified the paperwork. The final text proposed retaining ICANN as the IANA numbering operator under a contract with the five RIRs, with service levels, review, renewal and a route to termination. It proposed a review committee drawn from all regions. A group deciding who would hold the next contract needed more than a round of nods on a call. The 24-hour doorbell gave a specific person a specific chance to say: wait, that is not what our region agreed.
