TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	32ms	1806ms	400
7d	100%	100%	29ms	1839ms	2160
30d	100%	100%	29ms	1868ms	12016

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	95.00%	90.00%	334ms	2334ms	20
7d	100%	100%	332ms	506ms	120
30d	100%	99.70%	368ms	680ms	672

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%	116ms	118ms	30
7d	100%	119ms	146ms	150
30d	95.81%	188ms	442ms	836

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