How does down.now know if Quest Diagnostics is down?
Down.Now watches two crowd signals for Quest Diagnostics — anonymous reports submitted here, and public social-media posts about it — and compares the live volume against what's normal for that hour of the day. A sustained spike above that baseline opens an incident, which is usually visible before an official confirmation. We measure what users report, not Quest Diagnostics's servers directly.
