We aggregate two real signals for each side: user-submitted "down" / "working" reports tracked in 24-hour, 7-day, and 30-day windows, and detected incidents (continuous spikes flagged by our snapshot pipeline when reports cross a 3× baseline threshold). We don't fabricate uptime percentages or response times for sites we don't continuously probe.

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 chat.openai.com or deepseek.com from multiple regions on a schedule — continuous monitoring is a paid product for sites you own. This page reflects user-perceived issues only.
