TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks

7d	100%	100%	91ms	298ms	1752
30d	100%	100%	88ms	301ms	9756

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	69ms	89ms	48

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%	36ms	36ms	44
7d	50.00%	37ms	37ms	232
30d	50.00%	36ms	36ms	1312

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