Quad9 relocates DNS resolver operations to Switzerland to bolster privacy protections

Quad9, a free public DNS recursive resolver service focused on blocking malicious domains, has reorganized its operations to be based in Switzerland, citing the country's strong privacy laws. Industry figures from organizations including the Center for Democracy and Technology, ProtonMail, RIPE, and Alta Associates praised the move as a step toward diversifying and strengthening privacy protections in core internet infrastructure.

Mullvad to shut down public encrypted DNS servers, endorses Quad9

Mullvad announced it will shut down its public DNS-over-HTTPS servers, which it has operated since 2022, and redirect support to Quad9 instead. The company said running a privacy-focused public DNS service is highly specialized work best left to Quad9's dedicated team, and it will now fund Quad9 rather than duplicate its efforts. Mullvad Browser users on default settings will be automatically switched to Quad9, while manual configurations must be updated before November 2, 2026.
