Cache Reserve persistently serves static content from our global network, helping businesses lower their egress bills while ensuring higher cache hit ratios.

Improve your cache hit ratios by storing long tail content from the Cloudflare CDN.

Shield your origin servers from unnecessary, voluminous requests to ensure faster performance and a smoother user experience.

Maximize your savings by limiting unnecessary cache data evictions and eliminating associated egress costs.

Cloudflare Cache Reserve is a large, persistent data store built on R2 — our global, S3-compatible object storage service.

By serving static content from the edge of our global network, Cache Reserve helps increase cache hit ratios, speed up load times for end users, and minimize unnecessary egress fees.

"The 2% cache hit ratio improvement enabled by Cloudflare Cache Reserve has eliminated roughly two-thirds of our S3 egress activity. The reduction in egress charges is almost an order of magnitude larger than the price we paid for Cache Reserve. ”
