I’m very happy with Pi-Hole. However I’m surprised to have something like 80% or 90% of queries blocked because of one domain, device-metrics-us.amazon.com. It currently has 17,600 hits and the next one on the list is only 172 hits. I have a couple of Echos in my house and an Amazon Fire Tablet. Everything is working fine so I see no need to whitelist the domain. However, given the magnitude of requests, I’d like to ask: do you know what this domain is and why it’s requested so much?
