TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	70ms	128ms	252
7d	94.44%	94.44%	66ms	148ms	1074
30d	99.06%	99.06%	69ms	191ms	7686

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	105ms	160ms	40
7d	87.50%	87.50%	916ms	994ms	192
30d	98.15%	98.15%	275ms	337ms	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	100%	141ms	157ms	40
7d	93.48%	193ms	500ms	184
30d	98.44%	157ms	309ms	1286

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