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.

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.

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

Might be. VZ does host several big DNS root nodes. But it could just be comcast too...
