Activating the CDN will adjust the website's DNS settings. Because of the way the DNS works, it can take up to 24 hours for the customizations to be active everywhere and to be recognized by Website Checker.
If Website Checker still does not recognize the CDN after 24 hours, make sure the CDN is activated for the correct domain.
Please note: CDN is active for subdomains (e.g. www.your-domain.ca).
In order for your site to benefit from CDN, it must be accessible under a subdomain – ideally under www.your-domain.ca. If your website has a redirect from www.your-domain.ca to your-domain.ca, you need to disable this redirect to take advantage of CDN.
