Rollbacks are an interesting feature of the Jamstack that allow developers to recover from errors by reverting to a previous deploy in seconds. The concept is made possible by atomic and immutable deploy concepts, ensuring each deploy can function independently. In Netlify, rollbacks can be achieved by going to the Deploys tab, selecting the previous production deploy, and clicking publish deploy, restoring the site to its stable working state. This feature provides a safety net for developers, allowing them to quickly identify and fix issues without impacting users or causing reputational damage. Additionally, Netlify offers the option to lock publishing to a specific deploy, ensuring that changes do not inadvertently overwrite previously published versions.
