.abb SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	72ms	123ms	176
7d	94.07%	94.07%	68ms	124ms	940
30d	98.80%	98.80%	71ms	199ms	5344

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	94ms	107ms	24
7d	93.10%	93.10%	420ms	428ms	116
30d	59.28%	98.20%	157ms	167ms	668

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%	140ms	155ms	22
7d	93.22%	130ms	227ms	118
30d	98.21%	138ms	170ms	670

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