Dear RSSAC Caucus, This is a reminder for you to review the draft report on TTLs for the root zone. The review is due by close of business 15 June 2015. In particular in your review, it would be great if you could comment on: 1) whether there are any factual errors with the document. 2) whether you agree with the study methodology and the conclusions that are drawn from these studies 3) whether you agree with the findings of the report 4) whether you agree with the recommendations in this report 5) whether you have any advice on which of the mitigation options articulated in section 6.4.3 should be preferred? Also, are there any interest to have a briefing call on this report? Right now, the most likely time would be Monday 15 June. Thanks, Steve From: Steve Sheng <steve.sheng@icann.org> Date: Monday, June 8, 2015 at 1:37 PM To: "rssac-caucus@icann.org" <rssac-caucus@icann.org> Subject: [rssac-caucus] FOR REVIEW: DRAFT RSSAC Report on Root zone TTLs
Dear RSSAC Caucus,
On behalf of the caucus work party on Root Zone TTLs, attached please find for your review the draft RSSAC Report on Root zone TTLs. The work party is chaired by Duane Wessels, work party members include Joe Abley, Jaap Akkerhuis, John Bond, Brian Dickson, Shumon Huque, Warren Kumari, Duane Wessels (work party leader) and Matthew Thomas (invited expert). Staff support are: Steve Sheng, Barbara Roseman and Kathy Schnitt.
Root zone TTLs have not changed since 1999. In this report, the RSSAC caucus studies the extent to which the current root zone TTLs are still appropriate for today¹s internet environment. The report contains a number of findings and recommendations through four sets of empirical analyses. The work party chair invites you to give this report a careful review.
One thing the chair wish to highlight is that the work party discovered two potential problems related to the interaction between the SOA Expire value and the root zone¹s signature validity period. It also identified several mitigation options, and conducted a preliminary analysis of these options. However, the work party has yet to reach a conclusion to recommend which measure to take. It would be good to hear some feedback from the Caucus. Short of more definitive feedback from the Caucus, the work party will recommend further consultation in this area.
The work party chair requests you provide your review by close of business (anywhere around the world) 15 June 2015, if possible. This will allow the work party time to discuss and finalize the document in time for RSSAC consideration in Buenos Aires.
All the best, Steve
