How to Keep Front‑End Assets Available When a CDN Fails

When a CDN becomes inaccessible, a website's static resources can disappear, but by detecting failed CDN requests and automatically retrying them from the main domain—while preserving HTML, CSS, image, and especially JavaScript execution order—developers can ensure continuous site availability.
