Daily comparison reports created during the testing period are available on Verisign's website. Additionally, monthly progress reports for the testing period are available on ICANN's designated Root Zone Management System Parallel Testing webpage.
The authorization process step performed by NTIA will be removed upon the successful completion of the IANA Stewardship Transition, currently projected for 30 September 2016. Until then, the authoritative root zone file will continue to be produced by the production RZMS that contains the authorization step performed by NTIA.
