Hello,

Some geoDNS servers are not working:

Thanks @NTPman – the monitoring systems we use are somewhat oblivious to IPv6 (thankfully DNS generally is, too, or at least is resilient to this).

We can hopefully fix and if not then disable the IPv6 delegation to those servers (cc @gfk).

@ask, @gfk , thanks for taking care. There is another thing. Two geoDNS IP addresses are referred by multiple names:

c.ntpns.org has address 212.12.50.229
g.ntpns.org has address 212.12.50.229
d.ntpns.org has address 46.101.53.6
g.ntpns.org has address 46.101.53.6

Thanks for headsup @NTPman ! The ipv6 servers should be fixed now. As for the dups, it looks like g.ntpns.org is running stale data, I’ll see with @ask how to fix that!
