Once you’ve integrated your website with your chosen CDN, you can check if it’s working using these two methods:
Speed Test & URL Check — the simplest solution is to visit a speed test website that lets you input different locations.
There are a number of them to be found in a Google search, such as Web Page Test.
Choose a location and analyze the URLs of your site's static assets (content that servers don’t change, like images and video).
You should be seeing the CDN URL you listed during setup, if things are running as they should.
Page Source — view the page source (HTML) of your website.
For example, if you’re using the Chrome browser, right-click on a page to select ‘View page source’.
Scroll through the HTML, looking for static assets (e.g. files ending with .css, .js, .png, etc.).
The URL used to deliver those assets should be listed as the CDN URL you defined during integration setup.
If you’re not knowledgeable about the tech side of things and don’t have an IT team, you’ll want to choose a CDN supplier that has 24/7 Support, so you can always have peace of mind if you need them to check for you.
