Argo is a tool designed to make the internet faster and more efficient by observing network conditions and finding optimal routes across the internet. One of its features, Tiered Cache, reduces the number of data centers responsible for requesting assets from the origin server. Today, Cloudflare introduces Smart Topology, which maximizes cache hit ratios by identifying the single best data center for making requests to the origin. This feature is built on Argo's internal infrastructure and automatically configures itself once enabled by the customer. The topology selection algorithm minimizes cache misses and latency by choosing a proxying data center close to the origin server, ensuring network efficiency.
