Maintenance Mode for a Website in Power Pages

Maintenance mode in Power Pages allows administrators to temporarily restrict access to a website while performing updates, deployments, or troubleshooting activities. During this period, users can only access the system maintenance page.

When maintenance mode is enabled, visitors can only access the /_services/about endpoint while the rest of the site remains unavailable.
