[dns-operations] (co.)bw DNSSEC failure

[Peter van Dijk]

As (currently) visible on http://dnsviz.net/d/co.bw/dnssec/, -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.

See also, bad:
