Hi NZNOG, Time for an update with regards to ntp.net.nz servers. On the morning of Saturday Nov 22, ntp3.ntp.net.nz failed with a similar issue to that of ntp2.ntp.net.nz, this happened just a few weeks short of the new ntp2 go live. Due to this event we have pushed the new ntp2 appliance into service as well as reconfiguring another new appliance that was to be ntp4 as a ntp3 replacement. Both of these went live on Nov 22 at 18:06 hours, along with reverting the DNS ntp2 -> ntp3 redirection changes that were made in the July 14th email. As part of this the IP addresses for ntp2 and ntp3 have changed to the following ntp2.ntp.net.nz: 202.46.178.18 ntp3.ntp.net.nz: 202.46.179.18 ntp2 was unavailable via IPv6 prior to the failure, we have plans to resolve this in the near future. ntp3 is now unavailable via IPv6 due to the short time span of the work on Saturday, we hope to have this resolved in the coming weeks. We will update the list when IPv6 is back up and running. If you had previously used the IP addresses in your configs be sure to update them. We do recommend using the DNS names specified at https://ntp.net.nz to avoid this issue in the future. If you need any further information, please contact us at support(a)nzrs.net.nz Cheers Josh -- Josh Simpson Systems Administrator .nz Registry Services M: +64 21 783 399 P: +64 4 555 0124 GPG: 6516 B4EA 413B CAED 57B5 0956 124C 8AC3 A362 8080 www.nzrs.net.nz
