Content Delivery Network (CDN) in Power Pages

A Content Delivery Network (CDN) is a distributed network of servers that cache static website content closer to users to improve performance and reduce latency.

In Power Pages, enabling CDN ensures that images, scripts, and styles are served from the nearest edge location, improving load time and user experience.

Go to Power Platform Admin Center.
Select Power Pages Sites.
Open your website and go to Performance and Protection.
Turn on Content Delivery Network toggle.
Confirm the changes.

Enable CDN During Production Conversion

When converting a trial site to production, you can enable CDN during the conversion process.

You can disable CDN anytime from the Performance and Protection section in the admin center.
