Extend the DNS compliance tester do that it would be useful TLD operators to do staged warnings.
Extend the EDNS compliance tester so that it emits a staged warning stream at 120 days, 90 days, 60 days, 30 days, 15 days, 10 days, 5 days then daily for zones with broken servers.
This also needs to detect firewalls that are systematically blocking specific requests from packet loss. There needs to be a multi-day history of firewall detection before emitting the first warning.
It also needs to detect STD 13 (RFC 1034, RFC 1035) servers and not emit warnings if that is the only reason a server is otherwise flagged for EDNS protocol violations.
