How this was measured

This record comes only from RealUptime's own scheduled probes against SparkPost's public, unauthenticated endpoints, run from 10 named regions. It is never built from user reports or from SparkPost's own status page, and it does not change once this incident closes: this page is the permanent record, not a live view.
