How to Confirm Speed Layer Is Active

Purpose

This page explains practical ways to confirm that Speed Layer is running on your live site.

Method 1: View page source

1. Open your website in a browser.
2. View page source (most browsers support this from the right click menu).
3. Search for the Speed Layer script tag.

If you cannot find the tag in the source, it is likely not installed on that page.

Method 2: Use browser developer tools

1. Open your website.
2. Open Developer Tools.
3. Go to the Network tab.
4. Reload the page.

Look for network activity associated with Speed Layer. Depending on your configuration, you may see requests to Cloudflare services or a persistent connection that stays open during the session.

If you are comfortable with browser tools, this is often the fastest way to confirm the tag is executing.

Method 3: Compare behavior with and without Speed Layer

If your team supports a controlled rollout (for example by enabling Speed Layer for a subset of traffic), you can compare:

• How quickly key content appears
• How stable the layout is during load
• Whether interactions respond quickly

Use the same page type and device when comparing.

If you are not sure

If you have installed the tag and still cannot confirm it is active:

• double check the tag placement is on all pages
• confirm the change was published
• look for caching or delayed deployment behavior on your platform

Then use the troubleshooting checklist or contact support.
