Have I Been Pwned Speeds Up Dramatically with Cloudflare Edge Caching
2025-04-23

Have I Been Pwned (HIBP) dramatically improved its speed and availability by caching data on Cloudflare's global edge network. Previously, each query involved a long trip to an Azure function, but now data resides close to users. This reduces latency, boosts availability, and saves costs. While new data updates clear the cache causing temporary slowdowns, the overall architecture vastly optimizes HIBP's performance, enabling it to handle billions of queries.
