.abb SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	71ms	124ms	288
7d	100%	100%	71ms	179ms	1536
30d	99.92%	99.92%	72ms	182ms	8684

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	96ms	118ms	64
7d	100%	100%	96ms	117ms	344
30d	100%	100%	97ms	119ms	2000

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	155ms	66
7d	100%	140ms	156ms	352
30d	99.74%	142ms	192ms	1918

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