CDN Resolver Cache

CDN Resolver Cache is a networking performance layer that stores DNS answers for reuse until they expire for content delivery and edge caching. It uses TTL rules, cache keys, and invalidation so teams can reduce lookup latency while keeping evidence, reliability, and public-safe operational boundaries clear.

“The network engineering team used CDN Resolver Cache when a cache region served an asset, so the team could reduce lookup latency before traffic crossed a service boundary.”
