How we monitor

downforai.com probes each AI service every 2–5 minutes from multiple independent locations. We measure HTTP response codes, latency (p50 & p95), and endpoint availability across the surfaces listed above. Status is classified as Operational, Degraded, or Outage based on a weighted combination of probe results. Uptime is calculated over 30-minute buckets and the last 24 hours. User reports are factored into our diagnosis as a secondary signal. We are independent of all providers listed and receive no compensation to report any particular status.
