Anybody is seeing problems with Quad9 (9.9.9.9)?

My traceroute i extremely slow :

traceroute 9.9.9.9
traceroute to 9.9.9.9 (9.9.9.9), 64 hops max, 40 byte packets

Is Sonic aware of this ?

I have a pretty much identical trace, but no issues with DNS resolution:

Code: Select all

Strange traceroutes aren't always indicative of problems. Are you able to issue queries and get answers okay too?

Friendly reminder, Sonic's DNS resolvers are fast and on-network. 9.9.9.9 may have some advantages, but keep in mind that if you use it, all of your DNS requests are leaving Sonic's network and being sent over the internet in plain text for anyone in between to see and monitor your DNS traffic.
