You'd be surprised - I know of areas in Latin America and Asia that
are only allocating IPv6 addresses these days, and in Germany you
have
ISP's like Kabel Deutchland which only provide their customers with
IPv6 addresses now, unless you explicitly request an IPv4 address

And sure, in many cases they have some kind of fallback for IPv4
addresses, but they often favour IPv6 first and foremost - heck,
almost all of our browsers in openSUSE do that by default now also.

~20% of the traffic hitting google worldwide is IPv6 these days
https://www.google.com/intl/en/ipv6/statistics.html

That bumps upto 30% in Germany, and 33% in Greece & USA

So if something like conncheck.opensuse.org was responsive on IPv6
but
not responding properly, it's not surprising NM would go try a
different host rather than thinking "oh, maybe the webserver will
work
right on that old legacy protocol I don't like to use any more" ;)

as far as I know, the temp setup simply had no IPv6 - conncheck.o.o
only had A records (well, a CNAME record pointing to a host only having
A. same result)

Hence, it would really ONLY be valid for IPv6-only hosts having an
issue. As soon as the host also hasv4 connectivity, without V6 even
being advertised on DNS, it should just have worked.
