e.g. 1337x.to, limetorrents.cc and torrentking.eu bring up an "access blocked" page. "Access to this site has been blocked by an order of the Federal Court of Australia" etc.

https://thepiratebay.org is working fine for me today, although I'm sure that address hadn't worked for a while until very recently, and it wasn't the same sort of blocking as those above.

I have a new computer. On my old one I changed to Google DNS when a lot of torrent sites were being blocked a few years ago, and suddenly they all worked again. Kind of silly saying access is blocked when changing one number on the computer unblocks them all.

Those 3 all work for me (well the 3rd one gives a Cloudflare error at https://torrentrex.com/, not a DNS black hole). I am based in Sydney with my ISP's own DNS (Aussie BB).

I think I read somewhere that smaller ISPs aren’t required to implement the restrictions, Presumably they might choose to not manage their own dns servers thus significant overhead. but I could be wrong.

Tpb is definitely blocked, I didn’t notice for ages but turns out I was always overriding my ISP DNS and using google dns which for some reason doesn’t block it, I’ve since moved to cloudflare who are in the same boat.
