By transitioning the Cloudflare One Client to use QUIC streams for Proxy Mode, we eliminated the overhead of user-space TCP stacks, resulting in a 2x increase in throughput and significant latency reduction for end users.
We split a proxy application into multiple services to improve development agility and reliability. This blog also shares some common patterns we are leveraging to design a system supporting zero-downtime restart
Deploying new versions of long-lived server software while maintaining a reliable experience is challenging. For oxy, we established several development and operational patterns to increase reliability and reduce friction in deployments
We have recently introduced Oxy, our Rust-based framework for proxies powering many Cloudflare services and products. Today, we will explain why and how it spans various layers of the OSI model, by handling directly raw IP packets, TCP connections and UDP payloads
Secondary DNS Override is a great option for any users that want to take advantage of the Cloudflare network, without transferring all of their zones to Cloudflare DNS as a primary provider.
