Subject: [DNSOP] Fwd: Why is ns.coccaregistry.org returning REFUSED to DNSKEY queries?

ns.coccaregistry.org <http://ns.coccaregistry.org/> is serving 3 DNSSEC signed ccTLDs (AF, SB, TL) yet it is incapable of returning
DNSKEY records for those TLDs.  This will break DNSSEC validation for every lookup in those ccTLD
if this server is the only one reachable by the DNS clients.  This has been going on since at least April 2019.
