# ErrorPage
It Has Never Been Easier to Say That Something Went Wrong
{: .subtitle }
![ErrorPages](../assets/img/middleware/errorpages.png)
The ErrorPage middleware returns a custom page in lieu of the default, according to configured ranges of HTTP Status codes.
!!! important
The error page itself is _not_ hosted by Traefik.

!!! note
2019-09-03 16:02:05 +00:00
In this example, the error page URL is based on the status code (`query=/{status}.html`).
## Configuration Options
2019-04-03 12:32:04 +00:00
### `status`
The `status` that will trigger the error page.
The status code ranges are inclusive (`500-599` will trigger with every code between `500` and `599`, `500` and `599` included).
!!! Note
You can define either a status code like `500` or ranges with a syntax like `500-599`.
2019-04-03 12:32:04 +00:00
### `service`
The service that will serve the new requested error page.
2019-04-03 12:32:04 +00:00
### `query`
The URL for the error page (hosted by `service`). You can use `{status}` in the query, that will be replaced by the received status code.
