Every service, on the record. Checked by probes, never set by hand.

From automated probes, never from a person. The detection and forecast pipelines are judged by the freshness of what they publish, the API and the app by a request to their health endpoints, and the ground-truth job reports on itself. The page reads those results straight from public storage and refreshes every 30 seconds.

The API and the app are probed about once a minute. The detection pipeline is checked every two minutes, the ground-truth job reports every fifteen minutes, and the forecast pipeline is checked hourly. If a service has not written its status file in thirty minutes the page shows it as stale rather than healthy, because a probe that has stopped writing cannot vouch for anything.

Measured days come from live probe samples and are the only days counted in the uptime percentage. Reconstructed days were rebuilt after the fact from the pipeline’s own output records, from before the probes existed. They fill in the bar and are labelled as reconstructed in the day tooltip, but they are never counted as uptime, and hours that could not be verified are shown as unknown rather than as up or down.

The platform target is 99.9% availability per service, and each service card shows its error budget against that target over the measured window. A contractual commitment applies only to business agreements that include one; the free tier and trial accounts are provided on a reasonable-efforts basis. The terms of service set out the details.

Pending means the service has not published a status file yet, so there is nothing to show. Stale means its file exists but has not been written recently, so the last state cannot be trusted. Neither counts as healthy and neither counts as an outage: the page says what it can see and no more.
