NS sets differ

The nameservers at the parent and in the zone should be the same. Only at the parent: ns-1579.awsdns-05.co.uk. ns-115.awsdns-14.com, ns-1343.awsdns-39.org, ns-1579.awsdns-05.co.uk, ns-708.awsdns-24.net report NS ns-115.awsdns-14.com ns-1343.awsdns-39.org ns-708.awsdns-24.net.

#7
✓ No glue needed #8

All nameservers are outside the zone, so no glue records are needed.
✓ All names resolve #9

Every nameserver name has an address and is not an alias.
✓ Nameservers in different networks #10

The nameservers are spread over 4 IPv4 /24s and 4 IPv6 /48s.
i

All nameservers in one AS

All nameserver addresses are announced by one network operator (AS16509 (AMAZON-02 - Amazon.com, Inc., US): 8 addresses). An outage or attack on that network affects all nameservers; large anycast providers mitigate this, but a secondary DNS provider adds independence.

#11
✓ Nameserver names under 4 TLDs #12

Nameserver names use the TLDs .com, .net, .org, .uk.
✓ All reachable over IPv6 #13

Every nameserver has an IPv6 address.

Very low TTLs

These records have a TTL below 5m, causing extra queries and slower lookups: A (30s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.

#32
✓ No CNAME at the apex #33

The zone apex has no CNAME record.
✓ No wildcard #34

Names that don't exist return NXDOMAIN.

No CAA records

Without CAA records any certificate authority may issue certificates for this domain. A CAA record limits issuance to the CAs you use.
