.sbs SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	30ms	59ms	248
7d	100%	100%	28ms	48ms	1440
30d	99.92%	99.92%	28ms	129ms	7968

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	401ms	448ms	80
7d	100%	100%	402ms	441ms	480
30d	100%	100%	403ms	457ms	2664

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%	53ms	58ms	40
7d	100%	52ms	57ms	240
30d	100%	53ms	56ms	1338

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