Better HTTP/2 Prioritization for a Faster Web
HTTP/2 promised a much faster web and Cloudflare rolled out HTTP/2 access for all our customers long, long ago. But one feature of HTTP/2, Prioritization, didn’t live up to the hype. Not because it was fundamentally broken but because of the way browsers implemented it. Today Cloudflare is pushing out a change to HTTP/2 Prioritization that gives our servers control of prioritization decisions that

Cloud Computing without Containers
Cloudflare has a cloud computing platform called Workers. Unlike essentially every other cloud computing platform I know of, it doesn’t use containers or virtual machines. We believe that is the future of Serverless and cloud computing in general, and I’ll try to convince you why. IsolatesTwo years ago we had a problem. We were limited in how many features and options we could build in-house, we n
Serverless Rust with Cloudflare Workers
Update: Rust Tooling for Workers has improved significantly since this post. Go here to check out Wrangler, our new Rust+Workers cli The Workers team just announced support for WebAssembly (WASM) within Workers. If you saw my post on Internet Native Apps, you'll know that I believe WebAssembly will play a big part in the apps of the future. It's exciting times for Rust developers. Cloudflare's Ser
WebAssembly on Cloudflare Workers
We just announced ten major new products and initiatives over Crypto Week and Birthday Week, but our work is never finished. We're continuously upgrading our existing products with new functionality. Today, we're extending Cloudflare Workers with support for WebAssembly. All Workers customers can now augment their applications with WASM at no additional cost. What is WebAssembly? WebAssembly -- of
Introducing Workers KV
In 1864 British computer pioneer Charles Babbage described the first key-value store. It was meant to be part of his Analytical Engine. Sadly, the Analytical Engine, which would have been the first programmable computer, was never built. But Babbage lays out clearly the design for his key-value store in his autobiography. He imagined a read-only store implemented as punched cards. He referred to t

Introducing Cloudflare Registrar: Domain Registration You Can Love
Introducing Cloudflare Registrar: Domain Registration You Can Love Loading... “I love my domain registrar.” Has anyone ever said this? From before Cloudflare even launched in September 2010, our early beta customers were literally begging us: "Will you please launch a registrar too?!" Today we're doing just that, launching the first registrar we hope you’ll be able to say you love. It's built arou
On Firefox moving DNS to a third party | PowerDNS Blog
DNS lookups occur for every website visited. The processor of DNS requests gets a complete picture of what a household or phone is doing on the internet. In addition, DNS can be used to block sites or to discover if devices are accessing malware or are part of a botnet. (for the tl;dr, please skip right to the summary at the end) Recently, we’ve seen Cloudflare (rumoured to be heading to IPO soon)
The Road to QUIC
QUIC (Quick UDP Internet Connections) is a new encrypted-by-default Internet transport protocol, that provides a number of improvements designed to accelerate HTTP traffic as well as make it more secure, with the intended goal of eventually replacing TCP and TLS on the web. In this blog post we are going to outline some of the key features of QUIC and how they benefit the web, and also some of the
1.1.1.1 — the Internet’s Fastest, Privacy-First DNS Resolver
When the Internet was built, computers weren’t mobile. They sat in offices next to data centers. The Internet has changed but the assumptions made 30 years ago are making your experience slower and less secure. 1.1.1.1 with WARP replaces the connection between your device and the Internet with a modern, optimized, protocol.

Stupidly Simple DDoS Protocol (SSDP) generates 100 Gbps DDoS
Stupidly Simple DDoS Protocol (SSDP) generates 100 Gbps DDoS2017-06-28 Last month we shared statistics on some popular reflection attacks. Back then the average SSDP attack size was ~12 Gbps and largest SSDP reflection we recorded was: 30 Mpps (millions of packets per second) 80 Gbps (billions of bits per second) using 940k reflector IPs This changed a couple of days ago when we noticed an unusual
This Company Declared War on a Patent Troll With a $50,000 Bounty
This Company Declared War on a Patent Troll With a $50,000 Bounty A group of lawyers who formed a company called Blackbird to file patent lawsuits against tech and retail firms may have chosen the wrong target. On Thursday, that target—the Internet security company Cloudflare—responded to Blackbird’s legal action with a scorched earth campaign to take down Blackbird and shred its patents. In a blo
Introducing Cloudflare Orbit: A Private Network for IoT Devices
Introducing Cloudflare Orbit: A Private Network for IoT Devices2017-04-27 In October, we wrote about a 1.75M rps DDoS attack we mitigated on our network, launched by 52,467 unique IP’s, mostly hacked CCTV cameras. We continued to see more IoT devices in DDoS attacks, and so we started to put together a security solution to protect the devices from becoming part of the botnet in the first place. To
