## Known specifics

- **A failed delivery moves the subscription to `DEGRADED`.** Failed deliveries (the application's response is not `2xx` or the server is unavailable) are retried with increasing delay. After attempts are exhausted, the delivery moves to `FAILED`, the subscription is marked `DEGRADED`, and the owner receives a notification. The `recentDeliveries[].lastError` field shows the reason for the last failure.
