.dupont SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	4.0ms	20ms	264
7d	98.35%	98.35%	4.0ms	38ms	1440
30d	99.51%	99.51%	4.0ms	38ms	4860

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	169ms	222ms	20
7d	100%	100%	179ms	228ms	120
30d	100%	100%	165ms	206ms	404

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%	37ms	38ms	40
7d	100%	36ms	38ms	196
30d	100%	35ms	37ms	764

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