+title: Rollback a Release
+---
+
+As a maintainer, you may need to rollback a release if a deployment has gone wrong or if there are issues with the site. This document outlines the steps to rollback a release.
+
+Note: Do not use the Firebase UI to do this for hosting, as it will not rollback our serverless functions.
+
+Use the CircleCI to perform the rollback deployment so that we go through the same steps as a normal deployment.
+
+1. Access CircleCI Build Pipelines:
+
+   - Navigate to the CircleCI build pipelines interface.
+
+2. Locate the Desired Release:
+
+   - Use the search function to find the specific release you want to rollback to.
+   - Click on the corresponding build number to view its details.
+
+3. Access Workflow View:
+
+   - Once on the build details page, switch to the workflow view.
+
+4. Initiate Rerun:
+
+   - Identify the workflow corresponding to the release you wish to rollback to.
+   - Click on the "Rerun" button associated with this workflow.
+   - From the options presented, select "Rerun workflow from start".
+
+5. Optional: Selective Deployment:
+   - If you don't intend to deploy to all production environments, you have the option to cancel specific jobs after they've started.
+
+By following these steps, you can effectively rollback a release in your deployment pipeline using CircleCI.
