Where does this comparison data come from?

Two sources: (1) community reports submitted via the Report issue / Working buttons across our status pages, stored in our outage_reports table; (2) detected incidents from our snapshot pipeline, which flags anomalous spikes. We don't probe calendly.com or zendesk.com from multiple regions on a schedule — continuous monitoring is a paid product for sites you own. This page reflects user-perceived issues only.
