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.
