Deploying content updates to high-traffic WordPress sites has traditionally meant choosing between scheduled maintenance windows or accepting the risk of editing on the live-site — but modern CI/CD tooling changes that equation entirely. This talk walks through the architecture of a GitHub Actions and Bitbucket Pipelines workflow that orchestrates Zero Downtime Content deployment on Pantheon, using a content sync script built on native WordPress XML import functionality to keep sites fast and available throughout the process. Attendees will get a technical deep-dive into how pipeline automation handles sequencing, cache warming strategies, and sync across the deployment lifecycle without manual intervention. Whether you’re managing a single enterprise WordPress site or a large portfolio, you’ll leave with a replicable strategy for building content deployment pipelines that treat zero downtime as a hard requirement, not a best-effort goal.
