It sounds like your ISP has either suddenly blocked our site, or more likely, they have not updated their DNS Root zone, and as such, their DNS servers are pulling up a previous cached record for the site. The other possibility is that the DNS simply will not resolve the domain, which can also be the sign of a root zone issue.
Your best bet here would be to add the following lines to the hosts file in your computer. Those lines are:
185.30.166.2 www.gaytorrent.ru
185.30.166.2 forum.gaytorrent.ru
77.247.179.58 tracker.gaytorrent.ru
77.247.179.58 tracker.gaytorrent.tw
If you add these four lines to your system's hosts file, this should resolve the problem. If you're not sure of how to modify your computer's hosts file, I would encourage you to check out this comprehensive guide.
