Dear SubPro Implementation Review Team, This message is to inform you that ICANN org intends to publish a minor revision to the Registry Service Provider (RSP) Handbook. The current handbook (https://newgtldprogram.icann.org/en/application-rounds/round2/rsp/handbook) is version 1.2. The revision will be version 1.2.1. The purpose of the revised version is to address issues discovered by potential RSPs as they prepare to apply to the RSP Evaluation Program. The changes cover two questions regarding DNSSEC KSK Rollover, one question regarding Proxy RSP reporting, and the inclusion of a missing ICANN org Service Level Target (SLT). Questions MAIN.1.16 and DNSSEC.4.14 of the technical questionnaire require a Main RSP and a DNSSEC RSP to attest to annual KSK rollovers for each gTLD under management. The purpose of these questions is to ensure the regular practice of KSK rollovers in the event of an emergency. After careful consideration, ICANN org is changing these questions to free-text-form responses, as other strategies could allow RSPs to demonstrate that they are prepared for a KSK rollover. Additionally, doing an annual KSK rollover for every gTLD under management may not be operationally practical under certain scenarios. Question PROXY.7.6 of the technical questionnaire asks Proxy RSPs to describe their integration with ICANN’s Bulk Registration Data Access (BRDA) system, Registration Reporting System (RRI), and Zone File Access (ZFA) system. However, ZFA is not applicable to Proxy RSPs based on the current Standard Amendment Language Registration Validation per Applicable Law with Proxy (https://www.icann.org/en/system/files/files/standard-amendment-language-regi...), and ICANN org intents to strike ZFA from the information being sought in the question. Finally, the RSP Handbook does not list ICANN org’s Service Level Target for the Legal Compliance Check conducted during applicant onboarding of applicants to the RSP Portal. ICANN org intends to provide this information in the list of SLTs already present in the RSP Handbook. Thank you for your consideration. Regards, Gustavo Lozano ICANN
