Files that exist are cached by the CDN for a long time, but "file not found" and other error codes are intentionally cached only for a few minutes. Just because a file didn't exist on the origin server when you asked the CDN for it doesn't mean that we won't add the file to the origin server later, and we want the CDN to keep checking for that. We don't want the CDN to deliver a cached "file not found" error long after we added the file to the origin server.
