A CDN (Content Delivery Network) stores copies of your website's static files (images, CSS, JavaScript) on servers around the world. This speeds up your site by serving content from locations closer to your visitors. However, cached content can sometimes show outdated versions after updates. When to Clear CDN Cache Clear your CDN cache when: CSS or design changes aren't appearing. Updated images still show old versions. JavaScript functionality changes aren't working. After major content updates. When troubleshooting display issues Clearing CDN cache temporarily increases server load as the CDN rebuilds its cache. Avoid clearing during peak traffic times unless necessary. Setting Up CDN Management Via Kinsta Integration Connect Kinsta in the Integrations page. CDN management will be available automatically.

Browser cache: Client-side, affects individual users. Clearing CDN doesn't clear browser caches. Users may need to hard refresh (Ctrl+F5) for immediate updates Troubleshooting Cache Clear Fails Verify API credentials are correct. Check CDN Cache ID matches your site. Ensure Kinsta CDN is enabled for your site. Try again after a few minutes Changes Still Not Showing Wait 2-3 minutes for global propagation. Clear browser cache (Ctrl+F5).

No manual intervention needed to rebuild the cache.
