Our Comcast DNS keeps going in and out too, not clear if it is related or knock on effect or something else entirely.

I’m somewhat surprised you’re still using your ISP’s DNS when there’s ton of better free or paid options.

    Most users don't notice any real differences vs using their ISP DNS, and seeing it up and configuring it is yet another thing to take time or go wrong.

    Comcast doesn't let you change your DNS unless you run your own router. And they also rate limit you if you do.

      I’m on Comcast with a UniFi cloud gateway max with my DNS pointed towards adguard. I have not noticed any rate limiting. I actually don’t know how they would rate limit against DoH.

      Pretty sure you can do it at the individual device level, in the OS's network settings.

    We had edge delivery issues when I didn't use my ISP's DNS, especially from Apple. Not exactly sure of the mechanism, but downloading Xcode would take 2 hours instead of 10 minutes.

      That’s really weird that’s the case. DNS simply resolves “google.com” to an IP address (8.8.8.8 or something). Shouldn’t impact anything download related. I’m pretty sure DNS isn’t used for geolocating either

      Many reasons not do use the provided DNS. First, you don't want to give the ISP more information on your browsing habits than it can already gather otherwise. Second, in some countries, ISPs censor websites at the request of of the movie and music industries. Those are enough reasons to rely on a neutral DNS provider like Quad9 or your own DNS server.

      That’s… weirdly a thing.

      Do you use your car’s built in navigation function — that you paid for — or do you plug your phone in and use its free Google Maps or Apple Maps to navigate?
