We moved cdnjs, serving 9 billion requests a day, entirely onto Cloudflare's Developer Platform. That means we’re running one of the Internet's busiest open-source CDNs on our own building blocks, and we pushed Workflows and Workers limits higher for everyone.
Perhaps you’ve seen something that should sail out of cache get dragged back to the origin by a stray Set-Cookie or Cache-Control, headers that can be difficult to change on the origin itself. Cache Response Rules is the fix, applied at the right time.
Smart Tiered Cache allows for precise upper tier selection for origins hosted on AWS, GCP, Azure, and Oracle Cloud with customer-provided cloud region hints.
We are launching Workers Cache, a regionally tiered cache that sits directly in front of your Worker entrypoints. Infinitely composable, configured via standard HTTP headers
The explosion of AI-bot traffic, representing over 10 billion requests per week, has opened up new challenges and opportunities for cache design. We look at some of the ways AI bot traffic differs from humans, how this impacts CDN cache, and some early ideas for how Cloudflare is designing systems to improve the AI and human experience.
Rust-powered core systems, post-quantum upgrades, developer access for students, PlanetScale integration, open-source partnerships, and our biggest internship program ever — 1,111 interns in 2026.
This is part two of a story about how we overcame the challenges of making a complex system more scalable.
This blog post is the first of a series, in which we share our journey in redesigning Quicksilver — Cloudflare’s distributed key-value store that serves over 3 billion keys per second globally.
Following up on having the fastest purge in the industry, we have now increased Instant Purge quotas across all Cloudflare plans.
If you want to know what cache revalidation is, how it works, and why it can involve rolling a die, read on. This blog post presents a lock-free probabilistic approach to cache revalidation, along
Recapping all the big announcements made during 2024’s Birthday Week.
Speed Brain uses the Speculation Rules API to prefetch content for the user's likely next navigations. The goal is to download a web page to the browser before a user navigates to it.
We’ve built the fastest cache purge in the industry by offering a global purge latency for purge by tags, hostnames, and prefixes of less than 150ms on average (P50), representing a 90% improvement.
Today, we're thrilled to share that Cache Rules, along with several other Rules products, are generally available (GA). But that’s not all — we're also introducing new configuration options for Cache Rules
We introduced integrations with Supabase, PlanetScale, Neon and Upstash. Today, we are thrilled to introduce our newest additions to Cloudflare’s Integrations Marketplace – Sentry, Turso and Momento
Regional Tiered Cache provides an additional layer of caching for Enterprise customers who have a global traffic footprint and want to serve content faster by avoiding network latency when there is a cache miss in a lower-tier, resulting in an upper-tier fetch in a data center located far away
We have spent the last ten years learning how customers use Page Rules to customize their cached content, and it’s clear the time is ripe for evolving rules-based caching on Cloudflare
Cloudflare is uniquely positioned to help give crawlers hints about when they should recrawl, if new content has been added, or if content on a site has recently changed
