is to lsd.is: No valid RRSIGs made by a key corresponding to a DS RR were found covering the DNSKEY RRset, resulting in no secure entry point (SEP) into the zone. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (78.47.66.136, 78.47.136.183, 2a01:4f8:c2c:9f35::1, 2a01:4f8:c010:1a01::1, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)
is to lsd.is: The DS RRset for the zone included algorithm 14 (ECDSAP384SHA384), but no DS RR matched a DNSKEY with algorithm 14 that signs the zone's DNSKEY RRset. See RFC 4035, Sec. 2.2, RFC 6840, Sec. 5.11. (78.47.66.136, 78.47.136.183, 2a01:4f8:c2c:9f35::1, 2a01:4f8:c010:1a01::1, UDP_-_EDNS0_4096_D_KN, UDP_-_EDNS0_512_D_KN)

is/DNSKEY: No response was received from the server over UDP (tried 12 times). See RFC 1035, Sec. 4.2. (130.208.16.20, UDP_-_EDNS0_4096_D_KN)
