Privacy is, always has been, and always will be paramount at Quad9, so we want to take a few moments to explain the updates made to our privacy policy.
On 8 May 2026, Quad9 experienced outage intervals up to ~40 minutes for our primary zone “quad9.net” due to a failed validation step between our primary hidden authoritative servers and PCH’s anycast network, which we use for externally-facing DNS authoritative services.
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.
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 been chosen as one of the first recipients of the Nominet DNS Fund, which is designed to support the “unseen” work that keeps the internet running.
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 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.
