Evidence you can explore now
1,871 vendors with a verified current provider check. A fresh check shows source coverage; it does not qualify a reliability rating or prove every customer is unaffected.
Status reliability: 1,754 qualified records available →
What this view needs before ratings appear
Each grade needs at least 1,728 verified hourly observations within 90 days, 3 observed status changes and 3 matched provider notices. The table below shows provisional samples. These are observation-to-notice comparisons, not independent outage detections.
Unverified and legacy records do not count toward these requirements. There is no promised publication date: missing observations and unmatched notices can extend the wait.

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.
