CDN detection

We are in the process of cleaning up and optimizing our main site, but realized that for some reason CDN is almost never detected here.

technicians reviewed our setup to assure that all content was flowing through the cloudflare servers and they saw no issues. upon reviewing the scores here they were a bit perplexed why the site could not detect the CDN. Any ideas on what causes this?

The CDN not detected tests show the IP (on the table on the details page) as coming from your origin IP not Cloudflare. Was Cloudflare paused during these tests? I haven’t been able to replicate it with another test.

Also be sure to optimize those large jpg files on the home page, they should be about 1/3 of the current size.
