not_ready

The service is running but its database did not answer the readiness check.

HTTP 503.

Likely causes:

• The database did not answer within the check’s time limit (database: timeout).
• The database check failed (database: down).

What to do: Retry after a few seconds. Status checks use this to tell a database outage from a stopped service.

Retry: Yes. Nothing happened (or it was a read), so repeat it, after Retry-After when present.
