TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	59ms	124ms	195
7d	92.44%	92.44%	55ms	124ms	1030
30d	98.51%	98.51%	59ms	192ms	5850

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	103ms	127ms	40
7d	90.00%	90.00%	320ms	783ms	240
30d	61.01%	98.21%	83ms	180ms	1344

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	44
7d	93.22%	132ms	146ms	236
30d	98.36%	140ms	215ms	1340

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