DNS Resolvers Performance compared: CloudFlare x Google x Quad9 x OpenDNS
A couple of months ago I did a performance comparison between some of the top free DNS Resolvers available. It was just after Quad9 had launched and I was trying to decide which one to use and recommend to families and friends. Google, OpenDNS, Quad9, .. some many options… I love options … And things just got better. CloudFlare, one of the companies that know the most about Internet performance re
Announcing 1.1.1.1: the fastest, privacy-first consumer DNS service
Cloudflare's mission is to help build a better Internet. We're excited today to take another step toward that mission with the launch of 1.1.1.1 — the Internet's fastest, privacy-first consumer DNS service. This post will talk a little about what that is and a lot about why we decided to do it. (If you're interested in the technical details on how we built the service, check out Ólafur Guðmundsson
