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

Thu Sep 29 11:13:06 UTC 2016

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,
