CDN checker

What is checked

The domain's CNAME chain, matched against known DNS suffixes for major CDN providers (High confidence when matched), plus HTTP response headers and cookie/server markers those same providers commonly send (Medium confidence, since a header alone is weaker evidence than a DNS-level match).

Confidence is always shown, never hidden

Every finding states whether its evidence came from DNS or HTTP and how confident that specific piece of evidence is - a weak header-only match is never presented with the same certainty as a direct CNAME-suffix match.
