Dogfooding at scale: migrating cdnjs to Cloudflare’s Developer Platform

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.

BGP ORIGIN attribute manipulation and its impact on the Internet

By doing in-depth testing, we found nearly 70% of BGP paths experience ORIGIN attribute rewrites by transit providers seeking traffic advantages. We examine the global impact of this practice and argue for deprecating ORIGIN in route selection.

Introducing Cache Response Rules

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.

A broken DNSSEC rollover took down .al. Now 1.1.1.1 tells you when validation is bypassed

When a failed DNSSEC key rollover took down the .al TLD, we deployed a Negative Trust Anchor to restore resolution. This time, though, clients didn't have to take our word for it: 1.1.1.1 returned EDE 33, a new DNS error code that signals directly in the response that DNSSEC validation was bypassed.

Introducing Precursor: detecting agentic behavior with continuous client-side signals

Precursor, our new continuous behavioral validation engine for bot management, offers visibility into how humans and bots actually interact across the full user journey. By turning session-level behavior into bot detection signals, it identifies advanced automation with higher precision — while reducing friction for legitimate users.

Why we cannot wait for better post-quantum signature algorithms

NIST is advancing nine new post-quantum signature algorithms as potential candidates for future standardization. We take a closer look at all of them, and argue that while they are in the works and show great potential, we should use ML-DSA for now — the best currently available.

Making AI search smarter

Search is how we find nearly everything on the web — creators, merchants, answers. AI is rewriting the rules, leaving creators caught between staying discoverable in an agentic era and getting paid for their work. Today we're launching two initiatives to help.
