TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	145ms	211ms	231
7d	94.02%	94.02%	136ms	217ms	1287
30d	98.95%	98.95%	141ms	298ms	7348

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	40.00%	35.00%	213ms	2300ms	40
7d	33.33%	33.33%	438ms	1421ms	192
30d	32.10%	32.10%	243ms	1095ms	1296

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	50.00%	208ms	210ms	38
7d	47.41%	196ms	199ms	232
30d	49.40%	203ms	233ms	1332

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	2026-09-11 09:58

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