TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	18ms	39ms	352
7d	100%	100%	18ms	105ms	1860
30d	100%	100%	18ms	105ms	10468

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	41ms	135ms	48
7d	100%	100%	41ms	133ms	232
30d	99.35%	99.35%	42ms	125ms	1236

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%	28ms	28ms	66
7d	100%	28ms	28ms	346
30d	93.64%	27ms	28ms	1982

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