A lot depends on how your web site is blocked. It could be blocked by:
- specific domain name
- IP address
- port number
- protocol (HTTPS)
- geographic zone or country
- Unencrypted content
So you need to try to understand how your site is being blocked.
If the blocking country blocks HTTPS on 443 except for a list of approved commercial sites, there is a chance that you could run your site using HTTPS on a different port (possibly even port 80) and not be blocked. Unless you use port 80, you would need to put a link on your HTTP site to the HTTPS site in order for customers to find your site.
If your site is blocked by IP address or geographic zone, then there is a chance that you could avoid blocking by using a hosting service in a country that is perceived as neutral or friendly by the blocking country.
If your site is blocked by domain name, you could acquire a cert for a different domain name and set up an alternate site, with a link to it on your main site.
In the end, if your site is high-profile or perceived as high-ranking by the censors, they will eventually circumvent all of you efforts and block your encrypted site. The best that you can hope for is to make them work harder by continually changing the IP address, port number, domain name and hosting country.
