Improving Origin Performance for Everyone with Orpheus and Tiered Cache

This post introduces Tiered Caching as a free offering for all customers, dividing Cloudflare's data centers into a hierarchy of lower and upper tiers to improve cache hit ratios, reduce origin load, and enhance performance. It also announces the free availability of Orpheus, a system that routes around internet problems to ensure origin reachability by analyzing data from users on every path and ordering them per data center to eliminate connection errors and minimize packet loss. Orpheus improves origin reachability by 23% and reduces 522 errors. The post details how Tiered Cache works, its benefits (e.g., 60% reduction in cache miss rate), and how to enable it. It also explains Orpheus's mechanism and its synergy with Load Balancing, Cloudflare Network Interconnect, and Tiered Cache.
