Mullvad has operated public encrypted DNS (DoH) servers since 2022. They are unnecessary when using Mullvad VPN — traffic is already encrypted and Mullvad VPN's internal DNS handles all queries.
I use Quad9 where I can, but admittedly also have some reliability issues. Their local PoP will drop all requests for a couple minutes at least a few times a week. It’s shame since it’s the closest/best recursive resolver otherwise. CloudFlare is similarly close, but they don’t support EDNS, so I’ve had problems because of that.
