## Enable or disable external status checks **(ULTIMATE SELF)**

External status checks are:

- Under development.
- Not ready for production use.

The feature is deployed behind a feature flag that is **disabled by default**.
[GitLab administrators with access to the GitLab Rails console](../user/feature_flags.md)
can enable it.

To enable it:

```ruby
# For the instance
Feature.enable(:ff_external_status_checks)
# For a single project
Feature.enable(:ff_external_status_checks, Project.find(<project id>))
```

To disable it:

```ruby
# For the instance
Feature.disable(:ff_external_status_checks)
# For a single project
Feature.disable(:ff_external_status_checks, Project.find(<project id>))
```
