Zero Downtime Deployments

What Are Zero Downtime Deployments?

Zero downtime deployments ensure your website or application remains available throughout the deployment process.

How It Works

DeployHQ uploads your files to a new release directory, then atomically switches the symlink to point to the new release. This means there's no moment where your site is partially updated.

Requirements

  • SSH access to your server
  • Symlink support on your server
  • A compatible server configuration

Configuration

Enable zero downtime deployments in your server settings. You'll need to configure your web server to point to the symlink rather than the release directory.
