Does it also have a more detailed description of TEST12?

I believe the reference NTP source does not include man pages, so I
don't think a http://bugs.ntp.org/ report would be useful.  You might
check http://support.ntp.org/ to see if there's something you can add
or correct there about peers billboard sync codes.

However, both sites are currently inaccessible to me, which I reported
to webmaster at ntp.org but that mail may be hosted on the same
unreachable machine.  From three test locations I reach an ISC router
responding host unreachable which I think means the connectivity is
fine but the host isn't.  I'll forward the report on to a few selected
non- at ntp.org email addresses.
