I have seen this happen when bind for some reason (eg mtu issues with vpn) cannot query for the DLV key at dlv.isc.org. I have not figured out the exact failure mode there. Check the logs to see errors for DNSKEY queries for dlv.isc.org to see if this is happening here too. However in

It looks to me like your example, freebsd.org, is insecure. Yes, I agree freebsd.org is insecure, but I still want to be able to resolve it :-) .org is signed with NSEC3 and (I think, but could be misremembering) is using opt-out. org is registered in DLV, so BIND still has to do some work
