As of March 2017, around 10.78% of all the .ua domains were served via secured HTTPS protocol, with the Let s Encrypt Authority X3 being the most popular SSL certificate. Nginx is the most popular web server, serving 68.97% of the .ua domains, followed by Apache serving 17.75% of the total .ua domains.
