Quad9 lifts US Anycast local DNS resolution to 95%
Quad9 improved its US Anycast performance, achieving 95% local DNS resolution, up from 45%. This improvement was realized through its collaboration with i3D.net.
Key Takeaways
- Quad9 moved US Anycast local DNS resolution from 45% to 95%.
- The performance gain came from fixing routine inefficiencies in US Anycast traffic.
- i3D.net was the collaboration partner behind the improvement.
Why It Matters
Quad9’s US Anycast traffic now resolves locally 95% of the time, up from 45%, which directly improves the efficiency of its DNS path. For the broader delivery and networking stack, the story is about measurable infrastructure tuning rather than product launch rhetoric: a technical change produced a large routing gain. The next concrete signal to watch is whether Quad9 publishes similar local-resolution gains in other regions or reports further Anycast performance data beyond the US.
