# Readiness — are dependencies reachable?

`GET /health/ready`
Checks Postgres. Answers `503` when a dependency is down, which is the signal to stop sending this instance traffic without restarting it. Cache status rides along in the payload but never fails the probe — it is an optimisation, not a dependency. Queue depths ride along the same way: the API only ever produces, so a broker outage defers work rather than breaking a request. The process that cannot run without a broker is `tone-worker`, which refuses to boot instead of reporting here.
