“Why is my Pull Zone slow and my website even slower, even though I’ve implemented a CDN?”
There are plenty of tools available to help you troubleshoot why your site is running slowly. You can use a third-party website like Pingdom and WebPagetest, or you can use a browser extension like FireBug for Firefox. Regardless of which method you choose, run a test on your website and look for any files that return one of the following HTTP status codes: 404, 403, 304, 502.
- HTTP 302: The file has been moved. This is typically due to a redirection specified in the server’s .htaccess file. Check the file and remove the redirection.
- HTTP 403: You do not have permission to view the requested file. Check the file and directory permissions on your origin server to ensure it is able to be viewed on the web.
- HTTP 404: The requested file is not found. Check your origin server to make sure the file exists, and check the site’s source code to ensure the file is being linked properly.
- HTTP 502: Please visit the 502 troubleshooting page for more help.
- Another common reason for a slow Pull Zone is when your server is blocking traffic from the CDN as a part of mitigating a distributed denial of service (DDoS) attack. Our technical support staff can determine if this is the case, and if so they can assist you with whitelisting our IP ranges.
