Site purpose and operator signals
The page displays a list of links titled 'Замечания', 'Информатика', and '443', consistent with internal paths on a GitHub Pages educational repository.
The site's own contact details were not reviewed because the page text was not read in full.
Why the score is 82
The saved checks found no material threat, but the evidence was not strong enough for the highest Safe tier. Coverage remains separate so missing sources cannot be mistaken for clean results.

Web research findings
Independent findings for cs204.github.io, including public complaints, named review sources, registration records, and look-alike-domain evidence. A missing result is shown as unverified, never converted into a clean bill of health.
No independently sourced scam reports or credibility records were found for cs204.github.io. That is common for new or low-traffic sites and does not clear the site.

04 · Domain & Infrastructure
Domain & infrastructure
The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

Contact Verification
Saved contact details can help identify the operator. Their presence supports traceability; it does not prove the business is trustworthy.
Domain & Encryption
Certificate issued for *.github.io.
A shared content-delivery network address answers for many sites, so it is not the site's own server and says nothing about who runs it.
Scripts, fonts and CDNs

- jsDelivr
Payment providers the page loads
None seen among the outside domains we saved.
Read from the first 20 outside domains the page loads and the shop platform it uses; the web server and platform rows are under Hosting & Technology. A payment script on the page does not prove the shop accepts that method at checkout, or that you are protected.
