One method to determine if your website is being censored is to simply use a VPN(virtual private network) from another country to view your website. You can use proxy servers and the TOR browser/network as well. There are countries that have limited or no ISP(internet service providers), such as North Korea and Somalia. Unfortunately, there's no way of figuring out if you are censored in these places.
Now, you can do the old-fashioned way, and physically ask strangers from other countries to see if your website is censored. They can take screenshots/videos/information about your website and relay it to you. You can probably use carrier pigeons to relay information to each other. lol
Recommended VPNs: The cool part of mullvad and ivpn is that it doesn't require an e-mail to register an account. It is completely anonymous. You can send them cash(as low as $3-$5) in the mail to activate your VPN. They accept cryptocurrencies as well. Other payment methods are also accepted.
