No samples qualify for a combined success and latency score.

Evidence strength

No current issue evidence

No current corroborated or observed finding.

Evidence describes support for an issue, not its outage probability.

How this score works

100 × successful samples within the latency target ÷ assessed samples. Targets use a historical operation-latency baseline and are heuristic. Server failures count as failed samples; successful responses without a qualified target are shown separately. Only named operations are measured. Vendor statements, report volume, forecasts and incident records do not add score points.

A component issue stays visible even when other operations pass. Forecasts are separate from current health.
