Zero-Downtime WordPress Deployments

Zero-downtime deployment means releasing updates to a WordPress site without interrupting service or affecting users. In production environments, this ensures that visitors continue browsing, transactions complete normally, and no content or data is lost during new code deployment.

Traditional FTP-based or in-place updates often cause temporary outages, broken layouts, inconsistent plugin states, or database mismatches when files and schema change at different moments.

These failures can trigger cache corruption, lost form submissions, and revenue loss. A zero-downtime workflow eliminates these risks by controlling how code, assets, and data are released.

Themes, plugins, and configuration files live directly on the server, so updating them in place can create moments where code and database states don’t align.
