Errors from multiple -FRA nodes in Germany
Starting yesterday I'm getting errors from all of the Frankfurt (-fra) servers. It's intermittent and clears up after a couple seconds/minutes but happens again later:
^note the 2 errors at the bottom, these are usually 11ms ping, too
When this happened I ran a sh -c 'sh -c "$(curl -s https://nextdns.io/diag)"' but it stopped half-way through, I guess the diagnostic is affected by this problem, too.
I was connected to one of the servers that errored out earlier and with no DNS everything stopped working until the NDNS app switched to a different server.
Please advise.

Seems like an IPv6 related issue. If you ping other IPv6 resources (like 2001:4860:4860::8888), do you get errors as well when this happen?

NextDNS Thanks for your reply.
In true InterNet-bug-reporting-fashion the issue disappeared the minute I reported it here. :-]I'll follow up if it shows again. Cheers.

Valynor IPv6 weirdness :)

NextDNS It happened again while browsing the web, couldn't reach any sites for 20 seconds. This time it was IPv4 and v6.
Ping was working -
Anexia was just erroring out again and I started another diagnostic but it's freezing half-way through:
