Quad9 is enabling DNSSEC validation on its remaining non-validating resolver address. Starting June 15, 2026, DNSSEC strict validation will be active across every Quad9 service endpoint.

As part of our continuous efforts to improve the quality of the services we offer, we are migrating to a new Status Page platform effective April 22.

At Quad9, we aim to recognize the people behind the infrastructure that keeps the internet secure and reliable for millions of users worldwide. This staff highlight features Principal Engineer, Darren Kara.

Quad9 has enabled DNS over HTTP/3 (DoH3) and DNS over QUIC (DoQ) across its global resolver network.

Quad9 believes that DNSSEC is required for a secure DNS and will only implement Negative Trust Anchors (NTAs) for the shortest time possible when it believes the greater harm would come from taking no action.

Quad9 is looking for Threat Intelligence partners who specialise in regional threats in the Asian regions.

Quad9 provides security insights on the threats blocked by us between July and December 2025. This time we analyzed the top 25 domains blocked by us. The report combines DNS telemetry data and open-source intelligence with statistics and analysis to provide security insights on the top malicious domains visited by our users and blocked by Quad9 DNS.

Quad9 General Manager, Simon Forster, writes to express serious concern regarding emerging proposals that would require DNS resolvers to intervene in content enforcement actions.

Around the world, courts are increasingly allowing holders of intellectual property (IP) rights to shift the cost and burden of enforcement onto neutral third parties — including the organisations that keep the internet running.

Quad9 will be discontinuing support within DNS-over-HTTPS (DOH) using HTTP/1.1 on December 15, 2025.
