TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	69ms	217ms	252
7d	96.91%	96.91%	69ms	258ms	1164
30d	99.54%	99.54%	71ms	385ms	7776

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	359ms	1041ms	20
7d	90.00%	90.00%	1158ms	1375ms	120
30d	98.21%	97.77%	505ms	770ms	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%	132ms	134ms	22
7d	94.92%	125ms	127ms	118
30d	98.81%	131ms	148ms	670

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