.tax SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	35ms	90ms	264
7d	100%	100%	47ms	170ms	1440
30d	100%	100%	46ms	170ms	4860

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	92ms	165ms	20
7d	100%	100%	100ms	139ms	120
30d	100%	100%	100ms	142ms	404

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	96.88%	55ms	604ms	32
7d	100%	111ms	159ms	180
30d	100%	136ms	156ms	612

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