Hello,

Thank you for reaching out and I am happy to help!
The W3 Total Cache CDN serves static files from the CDN, meaning the JS, CSS, and images files are uploaded and served from the CDN, and the HTML files are still served from the origin.
Therefore, if you wish your entire website to be served from the CDN, you need to enable and use Full site delivery (FSD CDN). Full Site Delivery: Serve your entire site from a Content Delivery Network (CDN), ensuring faster load times worldwide.

I would recommend using Bunny CDN for the FSD integration or a regular CDN

Thanks!
