Hello,
it appears it is fixed now!
For those reading along, a point to clarify: it turns out there was no djbdns or tinydns was involved at all here, just an operator with a knack for funny version.bind strings.
Kind regards,

Hello,

I did not get a response to my subsequent explanation. Your configuration is broken and validating resolvers cannot resolve any domain inside co.bw. Can you please fix your signer/server? Thank you!

Kind regards,

As (currently) visible on http://dnsviz.net/d/co.bw/dnssec/<https://protect-za.mimecast.com/s/RE0WB2SeMq3Cl?domain=dnsviz.net>, -one- of
the auths for .bw (the one with ‘master’ in the name) responds
without any DNSSEC data to a DS query for co.bw, turning all names under
co.bw bogus if a validator happens to hit this auth.
