About Quad9
Quad9 is a Swiss non-profit resolver that blocks known malicious domains; 9.9.9.10 is the unfiltered variant.
NetTrace really queries every resolver separately, each with its own timeout. That shows you, for example, whether a DNS change has reached this provider yet, or whether a filter blocks your domain.
NetTrace is an independent service and is not affiliated with Quad9.
