Programmers are able to access blocked websites in several different ways by using the following techniques: using IP instead of URL, Anonymous Surfing, and by using Proxy in Browsers.
If the website is blocked on your end by some parental control software then you can boot you PC in safe mode wit networking and then access the blocked websites If the website is blocked on internet then you need to contact your ISP provider or website adminstrator.
It means you can't go there. It is blocked by the administrator.
Quite probably for the same reasons other organisations block access to websites. It is improper use of their network.

If use proxy server, client computers will first connect to the proxy server, requesting implement Internet access control, access blocked websites.
You could go through a proxy server to access blocked websites. Proxy websites are always being blocked so new ones always need to be made, you can do a Google search to look for working servers. The downside is that free proxy servers are usually slow and allow the remote computer running the server to access all of the data you are sending out.
Many websites require user authentication to access them. This is in order to create security for its members. With a username and password, users can be uniquely identified while having protection.
Revocation information for a security refers to data indicating whether a particular security certificate, key, or credential has been invalidated or is no longer trustworthy. This information is crucial for maintaining the integrity of secure communications, as it helps prevent the use of compromised or outdated credentials. Common methods for disseminating revocation information include Certificate Revocation Lists (CRLs) and the Online Certificate Status Protocol (OCSP). Ensuring access to up-to-date revocation information is vital for preventing unauthorized access and protecting sensitive data.
