What is a CDN?
A Content Delivery Network helps deliver website assets from infrastructure that may be geographically and technically separate from the origin server.
Short definition
A CDN distributes resources such as images, scripts, stylesheets or cached pages through a network of edge servers.
Simple example
A website may use Cloudflare, Fastly, CloudFront, Vercel, Netlify or a custom cdn.example.com host.
Why it matters for website checks
CDN hints can explain response headers, resource URLs, DNS records, caching behavior and why the visible server is not the origin.
Limits
A CDN signal does not prove who operates the website, what the origin server is or how every route is configured.
What does this mean for website owners?
Use the signal as a starting point for manual review. The website’s purpose, technical environment and actual configuration provide the necessary context.

FAQ
Is a CDN only for large websites?
No. Many small sites use CDNs automatically through hosting platforms or website builders.
Can a CDN hide the origin server?
Yes. That is normal for many setups, so CDN hints should be read as infrastructure context.
Why can CDN headers vary?
Cache status, edge region and proxy configuration can change by request, location and time.
