TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	149ms	210ms	484
7d	100%	100%	151ms	218ms	2640
30d	99.92%	99.92%	151ms	369ms	14586

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	35.00%	35.00%	332ms	1149ms	80
7d	35.00%	35.00%	251ms	997ms	480
30d	36.24%	36.17%	252ms	1023ms	2624

DNSSEC Validation Metrics

Registry Agreement Spec 6

DNSSEC is required by the Registry Agreement (Specification 6) but is not part of the Spec 10 SLA. We monitor DNSSEC validation independently.

Period	Validation Rate	RTT p50	RTT p95	Checks
24h	48.86%	207ms	427ms	88
7d	50.00%	208ms	211ms	480
30d	49.78%	215ms	247ms	2676

Unlike Spec 10 services, DNSSEC has no formal availability SLA. Thresholds shown are operational guidelines.

DNS Protocol Issues

Non-Compliant Behavior

These protocol issues were observed in the last 7 days and may affect DNS resolution or DNSSEC validation.

Issue	Nameserver	First Seen	Last Seen
`edns0_ignored` — EDNS0 OPT absent in NOERROR response	`ns3.uz`	2026-02-19 05:58	2026-04-15 18:58

Issues like rrsig_missing_udp indicate nameservers silently dropping DNSSEC signatures in UDP responses without setting the truncation bit, which breaks validation for resolvers.
