Custom maintenance page

When running Optimizely DXP, you can create a customized maintenance page to be displayed if you have to take down the site during, for example, deployments. Create an HTML page called maintenancepage.htm, and add it to your application's root directory for deployments.

This maintenance page cannot use any other files in the environment. Resources such as CSS, JavaScript, and images must be hosted elsewhere or embedded in the HTML file to be visible during maintenance.

Note

Before Optimizely Content Management System (CMS) version 12, the maintenance file size should be between 512 bytes and 1 MB. CMS version 12 removes this restriction.

A generic maintenance page is used if you do not add this file.
