Can Content Delivery Networks (CDNs) contribute to or mask 'status_in_page_errors'?

Yes, CDNs can contribute by caching outdated or incorrect content, leading to users seeing stale error messages even after the underlying issue has been resolved. CDNs can also mask errors if they are configured to serve custom error pages (HTTP errors) instead of passing the error directly from the origin server. Ensure CDN configurations are properly set to pass through error status codes appropriately when the origin server returns them.
