CDN Finder
Detect which CDN sits in front of a hostname (Cloudflare, Fastly, Akamai, CloudFront, etc.).
CDN detection for amscomputer.com
No CDN signatures matched.
The site appears to be served directly from origin, or uses a CDN whose fingerprint is not in our 18-vendor table.

About CDN Finder
This tool detects which content delivery network is serving a hostname by combining three signals: HTTP response headers (CF-Ray, X-Served-By, X-Amz-Cf-Id, and similar fingerprints), the CNAME chain in DNS (since most CDNs route via *.cloudflare.net, *.fastly.net, *.akamai.net, or similar), and the autonomous system number announcing the resolved IP. We currently match 18 vendors including Cloudflare, Fastly, Akamai, CloudFront, Azure CDN, BunnyCDN, Sucuri, Vercel, and Netlify.
When to use it
Use this before choosing a hosting plan to confirm whether a provider you are evaluating fronts their stack with a CDN by default. Run it on a competitor site to learn which CDN they trust for performance and security. Site owners use it during incident response to confirm whether a slowdown is at the CDN layer or the origin, since each layer has its own status dashboard worth checking.
How to read the results
Detection is strongest when all three signals point at the same vendor: the Server header says cloudflare, the CNAME points at example.cloudflare.net, and the resolved IP is in AS13335. Single-signal matches still indicate a CDN but with lower confidence. No detection means the site is served direct from origin, fronted by a CDN not in our 18-vendor table, or the operator has gone to effort to hide the layer.
Frequently asked questions
Why does the tool sometimes show no CDN even though I know one is in use? ▾
Some sites strip identifying response headers, use a private label CDN, or sit behind their own edge nodes with custom branding. We can only detect what we can see in headers, CNAMEs, and BGP. Smaller regional CDNs are also outside our 18-vendor table.
Can a site use more than one CDN? ▾
Yes, this is called multi-CDN. Sites route different traffic, regions, or asset types through different providers for redundancy and performance. The tool reports every vendor it detects, so multi-CDN sites typically show two or more entries with their evidence.
How is this different from BuiltWith or Wappalyzer? ▾
Those services maintain larger pattern databases and focus on application stack detection. This tool focuses narrowly on the CDN layer, uses three independent signals, and joins ASN evidence to our datacenter directory for context.
What does the CNAME chain tell me? ▾
It shows the DNS routing path from your hostname to the final answer. A chain like www.example.com -> example.map.fastly.net reveals the CDN sits between user and origin. A direct A record with no CNAME usually means no CDN, or a CDN that uses anycast routing instead of DNS-level delegation.
