Status
The measured success rate and latency of every engine we sample, over the last 30 days. A tool that sells measurement should show whether its own instruments are working, so this is public. A failed sample is excluded from your scores and counted here instead, never shown as a zero.
No measured runs in the window yet. This page fills in as engines are sampled; it never shows a fabricated uptime figure.
Success rate is completed samples over attempted samples per engine. Latency percentiles are over successful samples only, because a failed request is not a measure of how fast an engine answers. Figures refresh every few minutes.
