[nznog] ntp.net.nz ipv6?

Hi NZNOG folk, Is anyone else having issues with IPv6 connectivity to ntp1 and ntp2.ntp.net.nz via ipv6? ntp3 seems to be working fine. With the ipv4pocalypse upon us, I think this is a prudent reminder that when advertising services as available via IPv6, you should probably also be ensuring availability of the v6 connectivity as well.. I think we're certainly now past the point of this stuff being "niche" or "test" :) Cheers, Blair
