All of the lists were unknown for some time starting last night (GMT -6) -
not just "our germany list".  The server that hosts mailman went down in a
spectacular fashion.  It took a while to get it back up but it's running
again.  Items which complicated things:

   - that server's been running on the same VM since 2013
   - it's running an EOL/EOS OS (Ubuntu 10.04 - a 9 year old OS)
   - Rack's support does not cover Mailman and we're running an out of date
   version that is a major release behind current (2.x vs 3.x)
   - technically, Rack's support doesn't cover EOL/EOS OS'es but they still
   helped us get back online
   - the OS is so old, Rack's monitoring and backup agents are no longer
   supported nor run on the OS
   - the VM configuration and type used for that host is no longer offered
   by Rackspace causing complications which both caused the initial outage and
   complicated the restoring the server
   - since monitoring is no longer supported for that server, no alerts
   were sent when it went down
   - since the back agent can no longer run on a server that old, the most
   recent file-level backup is from July 17, 2017
   - Full VM image backups were still in place and working.  However,
   restoring those backups to different type and configuration of VM caused
   issues that took working with Rack's support team to get resolved.

Even with all those strikes against it, it's up and running again.  Not too
bad to have one (regrettably long) outage in 6 years.

Props to the several people on Rack's support team that helped me get the
Mailman VM back up and running as they were able to do the 'behind the
cloud'' work required to get the VM working again.

The system you seem to love to hate, Barracuda, spooled all the inbound
email and that is flowing again.  Once the retry period is over and that
spool is empty, things should return to normal. For a while, delivery of
emails that came in during the outage may be delayed a bit.  Barracuda,
BTW, is also unlicensed and continues to work without any agreement in
place.  Thanks to Barracuda for now cutting us off.

I also added a block volume to that VM to allow for a file-level backup
workaround as an interim solution while we wind down Mailman and retire it
this year.

When do we get a reliable mail delivery system for our lists?

Have you considered switching to Google Groups?  I'm pretty sure that
Google has a slightly larger IT staff and budget than OWASP does.  There's
also discourse.owasp.org which is a SaaS alternative we have in place as
well.  Or you could try the OWASP Slack instance too.

Thanks again for all your patience and understanding.

Cheers!
