Cache Reserve goes GA: enhanced control to minimize egress costs

Cache Reserve is a feature that allows customers with large content libraries to store their assets in Cloudflare's network for longer periods of time without being subjected to LRU eviction, thus avoiding origin egress fees. It achieves this by combining several Cloudflare technologies such as tiered cache and R2 storage. The configuration of Cache Reserve is simple and efficient, taking seconds on average. Since its launch, Cache Reserve has been updated with new analytics features, a way to delete storage without affecting the edge cache, and integration into Cache Rules for customizing what content should be eligible for storage in Cache Reserve.
