## Other responses

- `404` — Generation not found
- `503` — The node is temporarily unable to handle the request: either its request queues are saturated (overload protection) or it has not yet reached a stable mode. Overload protection is applied to every endpoint, so this response can be returned by any operation. The Retry-After header tells the client how long to back off before retrying.
