Welcome to Agents Week
Agents Week explores how cloud infrastructure must evolve to serve autonomous agents rather than human browsers. Join us as we unpack the storage, execution, and security primitives needed for an agent-native web.

Technical deep dives, product updates, and insights from the teams that are helping to build a better Internet.
An API for MoQ: provision your own isolated relays
Last year we made every Cloudflare server a Media over QUIC (MoQ) relay. Now the new provisioning API lets you create your own isolated relay and control who can publish and who can only watch.
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.
Post-quantum authentication to origins is now supported
Cloudflare now supports post-quantum (PQ) authentication when connecting to customer origin servers via Authenticated Origin Pulls and Custom Origin Trust Store. This is the first step towards providing PQ authentication for all Cloudflare products.
Natural disasters and government interference: examining Q2 2026’s major Internet disruption events
Cloudflare Radar tracked Internet disruptions driven by natural disasters, government-mandated shutdowns, and DNSSEC key rollovers over the last quarter. This post analyzes traffic telemetry to explain how these events impacted global connectivity.
We’re open-sourcing our privacy proxy CLI
pvcli is a curl-like tool designed to simplify the testing of complex privacy protocols like OHTTP.
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.
How the 2026 World Cup affected Internet traffic
We analyzed global HTTP traffic to explore how kickoff times, streaming habits, and hydration breaks reshaped online activity worldwide. From late-night traffic surges to halftime browsing spikes, here is how the world connected during the global tournament.
Cloudflare Internal DNS is now generally available
Cloudflare Internal DNS brings authoritative and recursive DNS for private networks to the same global network and control plane that runs Cloudflare's Zero Trust, networking, and public DNS.
Cloudflare WAF protects WordPress applications from two high-severity vulnerabilities
Cloudflare has deployed two WAF rules in response to high-severity vulnerabilities disclosed to us by the WordPress security team. The new rules protect all Cloudflare customers using affected WordPress versions, but customers should still update immediately to a patched release
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.
Improving Smart Tiered Cache for Public Cloud Regions
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.
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.
Introducing Meerkat: an experiment in global consensus
Cloudflare Research is building a global consensus service called Meerkat that uses a new consensus algorithm called QuePaxa. We plan to use Meerkat to build a strongly consistent, fault-tolerant key-value store, and other applications.
Cloudflare proudly joins the UK government's Cyber Resilience Pledge
The pledge is a voluntary framework inviting organizations to commit to foundational cyber security governance, board-level accountability, and supply chain rigor. For over a decade, Cloudflare has pioneered the core pillars of this framework: democratizing security, leadership accountability, and radical transparency.

Your Worker can now have its own cache in front of it
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
Unmasking the crawls with Attribution Business Insights
Cloudflare’s new Attribution Business Insights dashboard helps website owners understand crawler behavior, appetite, and potential value, fueling business-level conversations around crawl compensation.
