Seattle routing

My understanding is that there’s a Seattle DNS server that’s part of the global anycast network. However, I’m getting assigned to a non-Seattle dns server whenever I perform a test using https://dnsleaktest.com. Here’s my result:

Hostnames:

1. dns-edge-usa-central-utah.cleanbrowsing.org (108.171.217.194)

2. dns-edge-usa-west-sv.cleanbrowsing.org (144.202.108.20)

Any idea why? The side effect I noticed is I’m getting routed to CDNs that are far away from Seattle.

The SV ( Silicon Valley ) datacenter is pretty close to Seattle. Mind sending a traceroute to:

185.228.168.10

So we can see what is going on? also, what’s your ISP?
