Why check this
Confirm the platform first: Hosting & CDN decides what can be changed and whether it is worth it.
What this is
Tencent Cloud CDN (myqcloud / qcloud hosts and NWS headers) serves many China-region content and video sites. Confirming `x-nws-log-uuid` or `server: NWS_*` shows whether POP hit ratio and origin failures are masked at the edge. POP hit ratio and origin errors are easy to miss without the distinctive NWS headers.
How to tell from a public page
- [Tencent Cloud CDN] Asset hosts include `myqcloud.com` or `qcloud.com`.
- [Tencent Cloud CDN] Response headers include `x-nws-log-uuid`.
- [Tencent Cloud CDN] The `server` header uses an `NWS_` prefix.
- [Tencent Cloud CDN] Cache-status headers reflect POP behaviour.
How to read the result
Confirm when distinctive headers or qcloud hosts reproduce; a sales brochure does not qualify. Absence can mean another vendor sits outermost. Console screenshots pasted into blogs are not runtime proof. After a hit, verify HTTPS and HTTP/2 toggles.
What to do next
Tune purge strategy and compression, and compare with regional peers such as Alibaba Cloud CDN — open Alibaba Cloud CDN detector. Full audits return via run the full performance / images / SEO / accessibility audit on the home page. Prefer POP logs before changing origin capacity.

FAQ
How is Tencent Cloud CDN detected?
From structural signatures in the public HTML and response headers (domains, paths, attributes, scripts). Every verdict lists how many times each pattern matched — nothing is guessed.
Can the result be wrong?
If only a bare brand keyword matches without structural evidence, we label it \u201clikely\u201d instead of \u201cconfirmed\u201d — we would rather under-report than cry wolf.
Do you save the URLs I check?
No. The audit runs inside the request and the URL you paste is not written to storage. There are no third-party tracking scripts on the page either, so no log of who checked what exists. Copy the result yourself if you want a record.
Can a website hide what it is built with?
Partly, but rarely completely. The HTML sent to your browser, the response headers, script paths and asset structure have to be exposed to work, so there is always something readable. Server-side code, build config and private APIs stay invisible. That is why this tool reports the evidence it found rather than claiming a full picture. No match does not mean the technology is absent.
