Stephen,

Last SERVFAIL I logged was at

   Dec 26 12:42:58  UTC


My named queries.log file now has 30..60 entries per hour.

Thanks for fixing it.

Hey, I know that guy.

These are some long-running measurements related to a study on IPv6
hitlists: https://ipv6hitlist.github.io/

Measurement IDs are:

https://atlas.ripe.net/measurements/24304869/
https://atlas.ripe.net/measurements/24304870/

Probes with IPv6 will resolve the name and then run UDP and ICMP
traceroutes to the address in the answer, if they get one, much like
built-in measurements 6052 and 6152. They're configured to run on the
frequency of one resolution per measurement every two minutes.

I didn't investigate whether or how the DNS server was broken, but a few
moments ago I restarted the process and I can see that it's handing out
answers.

Cheers,

S.
