Interesting. UK ISPs have had a similar block/filter list for many years (mostly covering copyright-infringing torrent websites and the like). But it’s more robust than a simple DNS block. A VPN can bypass the block, but changing DNS providers will not.
- hsbauauvhabzb 9mo agoWhat / how do they do it then? SNI inspection?
- lategloriousgnu 9mo agoThe ISP's blackhole the IP for some blocked domains. So changing your DNS to 8.8.8.8 will resolve the domain, but the IP won't work. A VPN avoids this, since the traffic goes via the VPN IP.
- hsbauauvhabzb 9mo agoHow would that work with cloudflare and similar though?
- lategloriousgnu 9mo agoCloudflare works with the UK government to facilitate blocks within their infra, I assume in exchange for being allowed to access UK network infrastructure. In the case that a blocked site resolved to a Cloudflare IP, it would likely be kicked off of Cloudflare, or geo-blocked for UK users (by Cloudflare). https://www.ispreview.co.uk/index.php/2025/07/cloudflare-blocking-access-to-internet-piracy-websites-in-the-uk.html https://www.ispreview.co.uk/index.php/2025/07/cloudflare-blo...
- hsbauauvhabzb 9mo agoIronically that url is forbidden for me, I was under the impression that CF were fairly anti censorship, or at least they inferred that they should not be the one calling the shots (in reference to kiwifarms)
- nebezb 9mo agoWow that’s intense. I remember hearing someone complain on HN of their site getting blocked because it shared an IP with an illegal soccer livestream. I can’t imagine they’re doing this to IP blocks owned by CDNs like Fastly, CloudFlare, or CloudFront though. Or are they? Does this regularly break most of the internet for UK customers?
- xuki 9mo agoSpain ISPs block CloudFlare IPs during La Liga matches.
- uncletammy 9mo agoDo you have a source for this claim?
- jesuslop 9mo agoTBH it is not ALL cloudFlare IPs but a significant quantity of sites using and not using CF CDNs. You cannot imagine what a pest that is even for legit users of legit collateral damage pages. CloudFlare is in the courts appealing/countering initial court allowance to blockade and ISPs are bound to comply to blackout requests. You can look at https://hayahora.futbol https://hayahora.futbol (traslation: is there soccer match now?) to see affected domains.

- snvzz 9mo agoWhile I am not some reputable source per-se, I have some tailscale presence over there and can corroborate my exit nodes find cloudflare sites blanket blocked on weekends.

- ollybee 9mo agoIn that case it like someone controlling the DNS records for a banned site could cause some mischief
- flir 9mo agoI've never hit one. Flipping DNS works for (for example) Anna's Archive. Have you got an example?
- Aldipower 9mo agoTransparent DNS proxies on ISP side. Easy thing for them.
- hsbauauvhabzb 9mo agoDNS over HTTP is a thing also, though.
