Availability has been measured by calling the critical endpoints since Sep 17, 2026 (1903 checks).
A window that was not measured enough reads "No data". It is never filled in with 100%.
Availability
Share of probe runs in which every critical-path endpoint check that could be attempted succeeded (HTTP 2xx) AND the readiness gate passed. A run that attempted no endpoint check measures readiness only and is excluded from this figure.
Endpoints called: api-latest-rates, backend-health, backend-ready, public-rates.
Down window
2 or more consecutive failed checks. A single failed check is reported as a failed check, never as an outage.
Coverage
A window reports a percentage only once its checks span at least 1 day. Anything shorter reads as no data.
Error rate
Fleet 5xx share, using golden_signal_checker's own alert window and aggregation, sampled at each probe run. The counter table is pruned to that window, so this is a sample of the same quantity the alerting uses, not a reconstruction of a 90-day rate.
Last 7 days
6.99 of 7 days measured (99.8% of the window)
Last 30 days
13.29 of 30 days measured (44.3% of the window)
Last 90 days
13.29 of 90 days measured (14.8% of the window)
Readiness only (narrower)
Checks that recorded the /ready gate alone, with no endpoint call. This is the entire record from before endpoint probing began.
Rows before the availability series start recorded the /ready readiness gate only. They are published separately and are not counted in the availability figures above: /ready stayed green through the 2026-09-16 incidents, so those rows cannot be upgraded into an availability measurement after the fact.
