.tmall SLA Compliance

TLD SLA Compliance Metrics

Spec 10

DNS

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	71ms	227ms	16
7d	100%	100%	72ms	241ms	1424
30d	93.89%	93.89%	73ms	241ms	2000

RDAP

Period	Availability	RTT Compliance	RTT p50	RTT p95	Checks
24h	100%	100%	170ms	178ms	4

30d	100%	100%	171ms	177ms	288

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	8
7d	100%	135ms	153ms	218
30d	100%	136ms	153ms	301

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