Introducing Argo — A faster, more reliable, more secure Internet for everyone

This post introduces Argo, a "virtual backbone" for the modern Internet, which analyzes and optimizes routing decisions across the global Internet in real-time. It includes two core features: Smart Routing and Tiered Cache. Argo Smart Routing uses latency and packet loss data collected from each request that traverses Cloudflare's network to pick optimal paths across the Internet. Argo Tiered Cache uses the size of Cloudflare's network to reduce requests to customer origins by dramatically increasing cache hit ratios. It achieves this by first asking other Cloudflare PoPs if they have the requested content when a cache miss occurs, resulting in improved performance and reduced origin load. Customers enabling Argo can expect to see a 60% reduction in their cache miss rate as compared to Cloudflare's traditional CDN service. Argo also concentrates connections to origin servers, leading to fewer open connections and potential savings on cloud hosting bills.
