Reported uptime, 90 days

Where a platform published component state changes, the window is measured from those — when each component actually left and returned to operational. Otherwise it falls back to when the incident was opened and closed, which overstates it. Either way this is uptime as reported by the platforms, not independently measured: there may be outages nobody reported. Account-surface incidents and standing advisories are excluded, since neither is carrier API downtime.
