With the HTTP/3 RFC celebrating its 1st birthday, we examined HTTP version usage trends between May 2022 - May 2023. We found that HTTP/3 usage by browsers continued to grow, but that search engine and social media bots continued to effectively ignore the latest version of the web’s core protocol
When we first conceived of our aerial fiber deployment solution, Bombyx (the Latin name for a silk moth), we imagined a robot weaving strands of fiber-optic cables over powerlines, helping human workers quickly connect communities even in very rural or remote locations. Now, after years of successful research, Bombyx is taking the next steps in […]

Following the arrest of ex-PM Imran Khan, violent protests led the Pakistani government to order the shutdown of mobile Internet services and blocking of social media platforms. We examine the impact of these shutdowns on Internet traffic in Pakistan and traffic to Cloudflare’s 1.1.1.1 DNS resolver.
Introducing "Implement DNS in a Weekend"
There’s an important debate happening in Europe that could affect the future of the Internet. The European Commission is considering new rules for how networks connect to each other on the Internet.

Network Analytics v2 is a fundamental redesign of the backend systems that power Network Analytics
We split a proxy application into multiple services to improve development agility and reliability. This blog also shares some common patterns we are leveraging to design a system supporting zero-downtime restart
Starting today, you don’t have to be a network engineer to figure out what your Internet is good for. Let’s tell you how we’re doing it.
What the research is: Millisampler is one of Meta’s latest characterization tools and allows us to observe, characterize, and debug network performance at high-granularity timescales efficiently. This lightweight network traffic characterization tool for continual monitoring operates at fine, configurable timescales. It collects time series of ingress and egress traffic volumes, number of active f

We have recently introduced Oxy, our Rust-based framework for proxies powering many Cloudflare services and products. Today, we will explain why and how it spans various layers of the OSI model, by handling directly raw IP packets, TCP connections and UDP payloads
Historical guide for replacing Google Optimize with Vercel Edge Config and request-time routing, with current guidance for Routing Middleware and Vercel Functions.
Learn how Vercel enables streaming for serverless Node.js and Edge runtimes. HTTP streaming enables the server to incrementally send response data in smaller chunks to the client while generating the complete response.
In this blog post, we are proud to introduce Oxy - our modern proxy framework, developed using the Rust programming language
Introducing a new DNS platform that powers 1.1.1.1 and various other products.
Today we’re adding more flexibility to HTTP alerting, enabling customers to customize the types of activity they’re alerted on and how those alerts are organized.
Managing network solutions amidst a growing scale inherently brings challenges around performance, deployment, and operational complexities. At Meta, we’ve found that these challenges broadly fall into three themes: 1.) Data center networking: Over the past decade, on the physical front, we have seen a rise in vendor-specific hardware that comes with heterogeneous feature and […]
Adding new features to Cloudflare Zero Trust for Managed Service Providers using Gateway DNS.
Now Zero Trust administrators can use the familiar debugging tools that we all know and love like ping, traceroute, and MTR to test connectivity to private network destinations running behind their Tunnels
Cloudflare WARP can now securely detect pre-configured locations and route traffic based on the needs of the organization for that location.
In this post, we’ll recap how definitions of corporate network traffic have shifted and how Cloudflare One provides protection for all traffic flows, regardless of source or destination.
Today, we’re excited to announce a new way to use Cloudflare WARP to securely connect to and from any device in your Zero Trust deployment simply running WARP
VCR is a Ruby library that records HTTP interactions and plays them back to your test suite, verifying input and returning predictable output. Here’s how and when Prater (Staff Engineer) recommends you use it.
So what happened at all of those working group meetings, specification documents, and side events in 2022? What are implementers and deployers of the web’s protocol doing? And what’s coming next?
Today, we’re releasing DNS record comments and tags, making it easier to keep track of and manage DNS records of your domain
Is BGP safe yet? If the question needs asking, then it isn't. But how far the Internet is from this goal is what we set out to answer.
Cloudflare is participating in the AS112 project, becoming an operator of the loosely coordinated, distributed sink of the reverse lookup (PTR) queries for RFC 1918 addresses, dynamic DNS updates and other ambiguous addresses.
Historical announcement for the Edge Functions GA release, updated with current guidance for Vercel Functions, Fluid compute, and the Edge Runtime.
Historical announcement for Edge Config public beta, updated with current guidance for reading configuration from Vercel Functions and Routing Middleware.
After not raising prices in our history, this was something we thought carefully about before deciding to do. While we have over a decade of network expansion and innovation under our belts, what may not be intuitive is that our goal is not to increase revenue from this change.
In this blog we'll discuss how we manage Cloudflare IP addresses used to retrieve the data from the Internet, how our egress network design has evolved, how we optimized it for best use of available IP space and introduce our soft-anycast technology
Routing on the Internet follows a few basic principles. Unfortunately not everything on the Internet is created equal, and prepending can do more harm than good. In this blog post we’ll talk about the problems that prepending aims to solve, and some alternative solutions
Meta is deploying a timing protocol, Precision Time Protocol (PTP), that will offer new levels of accuracy and precision to our networks and data centers. We believe PTP will become the global standard for keeping time in computer networks. PTP will benefit today’s products and services and will be a foundational technology behind the development […]
Implementing Precision Time Protocol (PTP) at Meta allows us to synchronize the systems that drive our products and services down to nanosecond precision. PTP’s predecessor, Network Time Protocol (NTP), provided us with millisecond precision, but as we scale to more advanced systems on our way to building the next computing platform, the metaverse and AI, […]
