I want to share my Adguard DNS upstreamservers, they are mostly from germany, but all of them are european, no Cloudflare, no Google. You can easily copy / paste them into your Adguard. I only use DoT (DNS over TLS), everything is encrypted. Works fine since years

tls://anycast.uncensoreddns.org:853
tls://dns3.digitalcourage.de:853
tls://dot1.applied-privacy.net:853
tls://dns.digitale-gesellschaft.ch:853
tls://unicast.uncensoreddns.org:853
tls://dns.artikel10.org:853
tls://kaitain.restena.lu:853
tls://dns.quad9.net:853
tls://dns.sb:853
tls://dns.mullvad.net:853
tls://dot.ffmuc.net:853
tls://dot1.applied-privacy.net:853

And here are exactly the same as bootstrap servers:
