Rob,
Both domains you speak of do not rely on AMPRnet DNS
infrastructure
So Brandmeister and Dstar.su are not effected by any
DNS issues within AMPRnet

That is exactly what I wrote: it is not related to 44Net. There is nothing we can do
about it.
But it is related to amateur radio and it could affect people reading the list because
they are
involved in amateur radio networking. So it is good to know it so we know where we could
look
when problems appear.
See the topic of this thread: DNS Flag Day, Feb 1st, 2019. that is when problems could
occur.
Although I don't expect that all the Linux distribution maintainers will suddenly rush
out
resolver updates on Feb 1st, especially not on stable versions. So it could take longer
until
it becomes visible in our network. It will likely hit those that use 8.8.8.8 sooner than
e.g.
the resolver on our gateway (44.137.0.1) which will only get updated once Debian Jessie
receives
an update.

The problem lies outside of Linux distributions, the problem lies with
over aggressive firewalls (or poorly designed firewalls) that don't
allow or understand DNS Extensions.
As for 8.8.8.8 they were long ago EDNS0 compliant, as are all other
major Public DNS resolvers. IIRC, the problems will primarily hit old
Microsoft Windows DNS Servers that were coded so long ago that they
don't even know how to deal with DNS Extensions, and a handful of out-
of-date, or unmaintained, firewall equipment.
This email was sent to you from a Debian Stretch (earlier in the food
chain than Jessie) server using DNS servers running various versions of
Linux DNS software behind simple iptables firewalls that don't strip
off DNS Extension bits.
