Question

what unblocked websites securely has not blocked

Answer 1

I’m not sure I fully understand your question — do you mean “which websites are usually accessible (not blocked) on school/work networks and are secure?” or do you mean something else?

A few quick points before I list examples:
- Whether a site is blocked depends on the network (school, employer, public Wi‑Fi) and the organization’s filter rules. I can’t guarantee any site will be unblocked on your specific network.
- I can’t help with bypassing network controls (VPNs/proxies to evade filters). If a site is blocked and you believe it shouldn’t be, the right approach is to contact the network admin and request an exception.
- “Secure” generally means the site uses HTTPS, has a valid certificate (lock icon in the browser), and follows good privacy practices.

Commonly accessible, reputable sites that are often allowed on educational and many public networks:
- Wikipedia (en.wikipedia.org) — general reference
- Khan Academy (khanacademy.org) — free lessons and exercises
- Coursera (coursera.org) and edX (edx.org) — online courses
- Code.org, Codecademy (codecademy.com), freeCodeCamp (freecodecamp.org) — coding learning sites
- MDN Web Docs (developer.mozilla.org) — web developer documentation
- Stack Overflow (stackoverflow.com) — programming Q&A
- GitHub (github.com) — code hosting (may be restricted in some places)
- Google Drive / Docs / Sheets (drive.google.com / docs.google.com) — cloud docs (often allowed for productivity)
- Dropbox (dropbox.com) — file storage (may be restricted by some admins)
- BBC News (bbc.com), NPR (npr.org) — news sites (availability varies)
- LinkedIn Learning (learning.linkedin.com) — workplace learning (often allowed in corporate networks)

How to check site security and accessibility:
- Look for HTTPS and the padlock icon in the address bar.
- Check the certificate details if you’re unsure (click the padlock).
- Try accessing the site with your phone’s cellular data (not the network in question) to confirm whether the site itself is reachable.
- If a site is blocked but should be allowed for legitimate reasons, ask your network admin (provide URL and reason).

If you tell me the type of sites you’re looking for (education, news, coding, games, file sharing) and the environment (school, workplace), I can give a more focused list or help draft a polite request to your admin to have a site unblocked.
