Delivering Dot

Since March 30, 2017, Cloudflare has been providing DNS Anycast service as additional F-Root instances under contract with ISC (the F-Root operator). The collaboration aimed to enhance the security and speed of the root server system. Through telemetry measurements, it was observed that F-Root's performance significantly improved after transit was enabled to Cloudflare DNS servers. It became one of the fastest performing root servers, with a drop in 90th percentile response times. As F-Root picked up speed, DNS resolvers started sending it more traffic. One external DNS monitor reported that F-Root is now the fastest for roughly one quarter of the countries tested from.
