I bumped into at least one site blocked by cloudflare. When accessing the site, I’m redirected to:

https://www.cloudflare-terms-of-service-abuse.com/stream.ts

So far it happens when I try the landing page of the site, if I go pages I visited in the past I can reach the intended site. Maybe the name resolution is cached.

I haven’t tested it much but I’m using Quad9 and it’s not making any difference.

Cloudflare seems to be the SOA for the affected sites and then it sets *.ns.cloudflare.com as the primary source and dns.cloudflare.com as the administrator.

To my understanding Quad9, being a recursive DNS resolver, is not the main DNS authority in this case. Quad9 will reach out to cloudflare to refresh the records when the TTL expires and then cloudflare can return a different IP for the domain.

Either affected sites stop using cloudflare, or we reach them via TOR, if they have that option.

Turns out, my ISP has silently done a transparent DNS redirection. And their DNS servers are bad. Had to change to DoT to get it working. Something I should have done long ago anyway.

For me 1337x is not even loading. I see nothing, it just times out.

It does work if I connect to Cloudflare’s Warp.
