-## External pipeline validation service
-
-The [external CI/CD pipeline validation service](../../administration/external_pipeline_validation.md)
-is available for use on self-managed GitLab instances, but is not in use on GitLab.com.
-It is configured with [environment variables](../../administration/environment_variables.md)
-on the instance.
-
-To enable the feature on GitLab.com, enable the `ci_external_validation_service`
-[feature flag](../feature_flags/index.md). The valid "Not accepted" response code
-for GitLab.com is `406` only.
-
-For more details, see the linked issues and MRs in the
-[feature flag rollout issue](https://gitlab.com/gitlab-org/gitlab/-/issues/325982).
