QUIC (Quick UDP Internet Connections) is a new encrypted-by-default Internet transport protocol, that provides a number of improvements designed to accelerate HTTP traffic as well as make it more secure, with the intended goal of eventually replacing TCP and TLS on the web.
It's no secret that Cloudflare operates at a huge scale. Cloudflare provides security and performance to over 9 million websites all around the world, from small businesses and WordPress blogs to Fortune 500 companies. That means one in every 10 web requests goes through our network.
Using a VPN is painful: Logging-in interrupts your workflow. You have to remember a separate set of credentials, which your administrator has to manage. If you are away from the office, the VPN slows you down. Beyond just inconvenience, a VPN can pose a real security risk.
I still remember my first foray onto the internet as a university student back in the mid 90's. It was a simpler time back then, of course; we weren't doing our personal banking or our tax returns or handling our medical records so encrypting the transport layer wasn't exactly a high priority.
Back in April, I wrote about how it was possible to modify a router to encrypt DNS queries over TLS using Cloudflare's 188.8.131.52 DNS Resolver and a GL.iNet router; the folks at GL.iNet read that blog post and decided to bake DNS-Over-TLS support into their new router using the 184.108.40.206 resolver.
