This message is sent on behalf of the Number Resource Organization (NRO) ICANN and Regional Internet Registries Sign SLA for the IANA Numbering Services Helsinki, Finland – 29 June 2016. The RIRs and ICANN signed the Service Level Agreement (SLA) for the IANA Numbering Services today at ICANN 56 in Helsinki, Finland. This agreement documents the arrangements for provision by ICANN of IANA numbering services, after the IANA stewardship transition which is expected to occur on 30 September 2016. The SLA will only come into effect with the transition, and will have no effect whatsoever before that time. This event is a significant milestone in the long process of transition planning which started in March 2014 with US Government announcement. The process involved huge efforts by the Internet number community collectively, and by teams formed specifically to carry out the work. In particular the NRO Executive Council expresses its sincere thanks for the contribution by CRISP members during the last year and a half in the IANA Stewardship Transition Process. The CRISP Team worked tirelessly to integrate and consolidate the views from the five different regional communities into a single proposal. As the work of the CRISP team is now finally complete, we hereby announce that the team is formally dissolved. Finally the NRO EC also wishes acknowledge the support of the ICANN Board and staff who worked hard with us to finalise the SLA and ensure it was completed on time. The final version of the SLA is available at: http://www.nro.net/sla
