The link to the google document below is a “work in progress” to respond to the ICANN Board’s request: Whereas, the Board often requests advice from the Root Server System Advisory Committee (RSSAC) on matters that relate to the stability of the root zone, and often requests advice from the Security and Stability Advisory Committee (SSAC) on matters that relate to the security and stability of the Domain Name System (DNS) and often requests advice from the Root Zone Evolution Review Committee (RZERC) on architectural changes to the content of the DNS root zone Resolved (2018.05.13.09), that the Board requests RSSAC, SSAC and RZERC to provide the Board advices on “Updated Plan for Continuing the Root KSK Rollover” and associated plan documents, and report back to the Board by 10 August 2018 if possible. To this end, RSSAC has drafted the following response. We hope that the RSSAC Caucus can review and contribute this document to strengthen it further as necessary. We will be holding a discussion in the RSSAC meeting in an hour at 10:30 Panama time (15:30 UTC, June 28) about this document, and encourage anyone available to join the bridge and adobe connect room. Please feel free to add comments to the google document to suggest edits, comments, or missing information and conclusions. We will not be creating a separate mailing list for this discussion, so please use the main caucus mailing list if an e-mail discussion is needed. The timeline for responding to this is quite short, and there is not enough time to establish a formal caucus work party, but we are still hoping caucus members might be willing to contribute to this document. We must have the document complete by the end of July in order to submit it with enough time for the board to consider and act upon any information and advice within. Please note that the scope of our response is specifically limited to the effects of the KSK rollover on the Root Server System. Other groups within ICANN (SSAC and RZERC) will be responding to potentially wider considerations.
