If a website is unavailable for you, you can’t justify whether the website is inaccessible only for you or the entire country. One way to check whether the website is accessible for you are is through the ping command in the windows. To check the access of the particular website go to Run in windows and type cmd, then command prompt opens, type ping <website name> e.g., ping www.google.com , if the result of the packets lost is zero then website is accessible for you if the result is timed out then the website is not accessible for you.
Like wise if you want to check the status of the website in various countries you have to go just-ping website. Just type the web address which you need to check whether it is accessible in various countries and hit ping.
The results of the website accessible in 50 countries across the world is shown. I checked the results of the twitter website, china is the country which is inaccessible to twitter.China banned twitter because to control the raise of the protest against the government in country.
