## How to interpret this page

Estimated down reports are based on US Google Trends problem-intent searches. Values are relative activity from 0 to 100, not counts of submitted reports. The HTML chart averages samples into ten-minute intervals. Partial samples are excluded and missing samples are not invented.

Recorded outage reports and estimated activity are separate signals. Neither confirms that every user is affected. Missing or stale data does not establish that a service is working.
