# Cut-off dates of an observatory

> Returns the cut-off dates of the loaded data and of each source, with the footer text of the boards.

> [!NOTE]
>
> It reads the same ClickHouse tables as
> [Board data](https://help.impactu.colav.co/en/api-reference/observatory/get-bundle.md): without them it
> returns `503`. It requires no authentication.
