# service_unavailable

> The data couldn't be read

- Status: 503 Service Unavailable
- Returned by: /api/public
- Retry (`retryWhen`): `same_request`
- Did anything happen? (`outcome`): `none` (It did not happen)
- Rivr's services
- Page in the portal: https://developers.rivr.io/errors/service_unavailable
- Try it: `GET https://developers.rivr.io/errors/simulate/service_unavailable` answers with the code's exact wire form; `?succeedAfter=N&attempt=K` gives a 200 once `attempt` passes `N`

## What it means

Data Rivr needs for the request couldn't be read right now, for example the clinic's details, and nothing was done. `message` is the same text as before.

## What your system does

Try again in a while.

## Is it worth retrying?

Yes. The same call can succeed in a while.

`retryWhen`: `same_request`. Send the very same request again, unchanged: the same `Idempotency-Key` and the same order id. Wait `Retry-After` seconds when the answer has the header, otherwise a short while that grows with each attempt.

## Did anything happen?

`outcome`: `none`. **It did not happen.** This call did not do what you asked for and changed nothing else that you can see or that concerns money. Where the code has an `outcomeNote`, it takes precedence.

## Example: /api/public

```http
HTTP/1.1 503 Service Unavailable
Content-Type: application/json

{
  "propertyName": "Merchant",
  "message": "Klinikens uppgifter kunde inte läsas just nu. Försök igen om en stund.",
  "errorCode": "service_unavailable",
  "code": "service_unavailable",
  "type": "https://developers.rivr.io/errors/service_unavailable"
}
```

The `title`, `detail`, `message` and `error_description` texts are exactly as the API writes them today.
