Hello: Starting in July 2018 InternetNZ has been monitoring and measuring how .nz domains will be affected by DNS Flag day. For those who don't know, DNS Flag Day, or 1 February 2019, has been set by a number of DNS software developers as a coordinated day to release new DNS software versions. The changes will remove DNS protocol workarounds related to EDNS. You can find more information at https://dnsflagday.net InternetNZ has been actively notifying affected DNS Operators, Registrars and Registrants in the past weeks, and the situation has greatly improved. If you haven't tested your authoritative nameservers, we strongly suggest you do. There are still a few high profile .nz domains affected. I'll be presenting about this topic during the next NZNOG meeting in Napier, with a description of what's changing, how the problem has been evolving for .nz and other interesting bits and pieces. There are a number of DNS software implementors involved, as well as a number of ccTLDs measuring and campaigning to reduce the number of domains affected. If you have any questions or comments, feel free to contact me. Cheers, -- Sebastian Castro Chief Scientist @ InternetNZ desk: +64 4 495 2337 mobile: +64 21 400535
