.mtr SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	158ms	212ms	264
7d	100%	100%	158ms	214ms	1440
30d	99.92%	99.92%	157ms	354ms	7924

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	0.00%	0.00%	572ms	10007ms	72
7d	0.00%	0.00%	586ms	10006ms	360
30d	0.00%	0.00%	588ms	10008ms	2016

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%	207ms	229ms	66
7d	100%	207ms	229ms	360
30d	99.70%	205ms	257ms	1988

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