How we grade transparency
Grades summarize consistency between two records from an official provider source: when ServiceAlert observed an operational-to-disrupted status change and the incident-notice time reported by that source. The observation timestamp is a polling time, not the provider’s exact change time or an independent outage detection. Small or incomplete samples are shown as Provisional.
