Cache Reserve

Serve static content faster and save on egress costs

Cloudflare Cache Reserve is a large, persistent data store built on R2, our global S3-compatible object storage service. It helps businesses lower their egress bills while ensuring higher cache hit ratios. With Cache Reserve, you can maximize the cache lifetime of your resources, customize cache settings, and accelerate content performance across our global network.

Boost Cache Hit Ratios

Improve your cache hit ratios by storing long-tail content from the Cloudflare CDN. This helps businesses lower their egress bills while ensuring higher cache hit ratios and optimizing storage costs.

Enhanced Content Delivery

Cloudflare's global network caches your static content 50 ms from 95% of all Internet users, ensuring fast load times and a better user experience.

Cost-Effective Storage

Maximize your savings by limiting unnecessary cache data evictions and eliminating associated egress costs. This helps you lower cache 'misses' and optimize your storage for better performance.
