>We want a public service to be available. Going forward, we will support Quad9 instead of running it ourselves. Running a privacy-focused public DNS service is a highly specialized undertaking, and the Quad9 Foundation is the undisputed leader in the field. Rather than duplicating their efforts to achieve only part of what they do, we're putting those resources toward financially supporting Quad9 instead.

Brilliant.

On the Quad9 website:

>Since Quad9 already performs DNSSEC validation, DNSSEC being enabled in the forwarder will cause a duplication of the DNSSEC process, significantly reducing performance and potentially causing false BOGUS responses.

This sounds dodgy. Surely that means Quad9 can poison my DNS?

Not if Quad9 is using DNSSEC, no.

What's the specific threat you're envisioning? If it involves Quad9 themselves being malicious, what would DNSSEC on the forwarding prevent?

I'm all for supporting quad9; but what if we just disable dnssec instead, it really solves nothing and continued support of it just makes it show up in compliance guides unnecessarily.

disappointing, because alternatives matter too. quad9 and other well known servers are potentially blocked by some countries, so the more lesser known services there are the better.

Mullvad talks a lot about decentralization, then hands its resolver users to one of the biggest resolvers going. Quad9 is a good operator, and they actually fought Sony in German court instead of quietly complying. They still got ordered to block. That's the problem. A blocking order only hurts as much as the resolver it lands on is used, so every operator that shuts down and sends its users to Quad9 makes the next order a better deal for whoever files it.

Quad9 doesn't have an adblocking DNS service though, so it's not really a replacement.
