Improving Smart Tiered Cache for Public Cloud Regions

Cloudflare announces Smart Tiered Cache for Public Cloud Regions, a feature that lets customers set cloud region hints for anycast or regional-unicast origins (AWS, GCP, Azure, Oracle Cloud) so Cloudflare can map provider IP ranges to the correct region and choose optimal primary and fallback upper-tier PoPs. The post explains how Cloudflare detects anycast by comparing multi-point probe latencies, how it builds region-to-upper-tier mappings from provider IP range files and continuous probing, and that configuration is available in the dashboard, API, and Terraform to reduce hairpinning and improve cache efficiency.
