| A few weeks ago I noticed DNS4EU couldn’t resolve archive.is and assumed it was just a configuration mistake. I emailed them about it, and after a couple of days or weeks (not really sure) the domain started resolving again. Given AdGuard’s recent report about suspicious pressure on DNS providers to block Archive.today, I’m starting to wonder if DNS4EU’s temporary block was actually related to the same campaign |

| member of DNS4EU ops team here - This was not the case, we had reachability issues with the authoritative servers of archive.is and had to reach out to the team to allow our source IPs. https://www.reddit.com/r/BuyFromEU/comments/1ohekv5/updatedn... |

| Archive.is have previously blocked cloudflare DNS because it was anonymizing requests. It could be either. https://news.ycombinator.com/item?id=19828317 >The archive.is owner has explained that he returns bad results to us because we don’t pass along the EDNS subnet information. This information leaks information about a requester’s IP and, in turn, sacrifices the privacy of users. |

| ▲ | ndiddy 4 hours ago | parent | next [-] | | Someone asked the archive.is owner why he does this in the past. It's because of similar situations to this one where someone who wants to get archive.is taken down uploads illegal content, requests archive.is to save it, and immediately reports archive.is to their country's legal authorities. His solution to this is using the EDNS information to serve requests from the closest IP abroad, so any takedown procedure requires international cooperation and therefore enough bureaucratic overhead that he gets notified and has time to take the content down. https://news.ycombinator.com/item?id=36971650 I also find the "we don't want to leak a requester's IP" explanation for blocking EDNS to be suspect. The way DNS works is that you ask for the IP address for a domain name, you get the IP, and then you connect to it. With Cloudflare's DNS, the server doesn't know your IP when you do the DNS lookup, but that doesn't matter because you're connecting to the server anyway so they'll still get your IP. Even if you're worried about other people sniffing network traffic, the hostname you're visiting still gets revealed in plaintext during the SNI handshake. What Cloudflare blocking EDNS does do is make it much harder for competing CDNs to efficiently serve content using DNS based routing. They have to use Anycast instead, which has a higher barrier to entry. | | |

| ▲ | Buge 5 hours ago | parent | prev [-] | | Here's my speculation on the underlying reason archive.today blocks Cloudflare DNS: https://webapps.stackexchange.com/a/135229/229725 I speculate it's due to archive.today wanting granular (not overly broad) legal censorship compliance. Which is somewhat related to this post. |
