.barclaycard SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	72ms	123ms	84
7d	95.41%	95.41%	68ms	154ms	436
30d	99.21%	99.21%	72ms	192ms	2540

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	95ms	146ms	40
7d	97.56%	97.56%	231ms	286ms	164

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	156ms	22
7d	93.33%	132ms	146ms	120
30d	98.66%	139ms	185ms	670

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