Cloudflare Pages is now Generally Available
Cloudflare Pages is now Generally Available Loading... In December, we announced the beta of Cloudflare Pages: a fast, secure, and free way for frontend developers to build, host, and collaborate on Jamstack sites. It’s been incredible to see what happens when you put a powerful tool in developers’ hands. In just a few months of beta, thousands of developers have deployed over ten thousand project
Introducing Cloudflare Pages: the best way to build JAMstack websites
Introducing Cloudflare Pages: the best way to build JAMstack websites Loading... Across multiple cultures around the world, this time of year is a time of celebration and sharing of gifts with the people we care the most about. In that spirit, we thought we'd take this time to give back to the developer community that has been so supportive of Cloudflare for the last 10 years. Today, we’re excited
Introducing Workers Unbound
We launched Cloudflare Workers® in 2017 with the goal of building the development platform that we wished we had. We want to enable developers to build great software while Cloudflare manages the overhead of configuring and maintaining the infrastructure. Workers is with you from the first line of code, to the first application, all the way to a globally scaled product. By making our Edge network
Ladies and Gentlemen…Cloudflare TV!
I'm excited to announce the upcoming launch of Cloudflare TV. A 24x7 live television broadcast, streamed globally via the Cloudflare network. You can tune in to the pre-broadcast station and check out the upcoming schedule at: cloudflare.tv I'm kicking off the first live broadcast starting at 12:00pm Pacific (1900 UTC) on Monday, June 8 with a conversation with Chris Young (add to calendar).

Cloudflare Workers Now Support COBOL
Recently, COBOL has been in the news as the State of New Jersey has asked for help with a COBOL-based system for unemployment claims. The system has come under heavy load because of the societal effects of the SARS-CoV-2 virus. This appears to have prompted IBM to offer free online COBOL training. As old as COBOL is (60 years old this month), it is still heavily used in information management syst
Why Cloudflare Chose AMD EPYC for Gen X Servers
Why Cloudflare Chose AMD EPYC for Gen X Servers Loading... From the very beginning Cloudflare used Intel CPU-based servers (and, also, Intel components for things like NICs and SSDs). But we're always interested in optimizing the cost of running our service so that we can provide products at a low cost and high gross margin. We're also mindful of events like the Spectre and Meltdown vulnerabilitie
HTTP/3: the past, the present, and the future
HTTP/3: the past, the present, and the future Loading... This post is also available in 简体中文, 日本語, 한국어, Français, Español. During last year’s Birthday Week we announced preliminary support for QUIC and HTTP/3 (or “HTTP over QUIC” as it was known back then), the new standard for the web, enabling faster, more reliable, and more secure connections to web endpoints like websites and APIs. We also let
WARP is here (sorry it took so long)
Today, after a longer than expected wait, we're opening WARP and WARP+ (plus) to the general public. If you haven’t heard about it yet, WARP is a mobile app designed for everyone which uses our global network to secure all of your phone’s Internet traffic. We announced WARP on April 1 of this year and expected to roll it out over the next few months at a fairly steady clip and get it released to e
Details of the Cloudflare outage on July 2, 2019
Details of the Cloudflare outage on July 2, 2019 Loading... Almost nine years ago, Cloudflare was a tiny company and I was a customer not an employee. Cloudflare had launched a month earlier and one day alerting told me that my little site, jgc.org, didn’t seem to have working DNS any more. Cloudflare had pushed out a change to its use of Protocol Buffers and it had broken DNS. I wrote to Matthew
Introducing time.cloudflare.com
Cloudflare has always been a leader in deploying secure versions of insecure Internet protocols and making them available for free for anyone to use. In 2014, we launched one of the world’s first free, secure HTTPS service (Universal SSL) to go along with our existing free HTTP plan. When we launched the 1.1.1.1 DNS resolver, we also supported the new secure versions of DNS (DNS over HTTPS and DNS
Announcing AMP Real URL | The Cloudflare Blog
The promise of the AMP (Accelerated Mobile Pages) project was that it would make the web, and, in particular, the mobile web, much more pleasant to surf. The AMP HTML framework was designed to make web pages load quickly, and not distract the user with extraneous content that took them away from focusing on the web page’s content. It was particularly aimed at publishers (such as news organizations
Monsters in the Middleboxes: Introducing Two New Tools for Detecting HTTPS Interception
Monsters in the Middleboxes: Introducing Two New Tools for Detecting HTTPS Interception Loading... The practice of HTTPS interception continues to be commonplace on the Internet. HTTPS interception has encountered scrutiny, most notably in the 2017 study “The Security Impact of HTTPS Interception” and the United States Computer Emergency Readiness Team (US-CERT) warning that the technique weakens
HTTP/3: From root to tip
HTTP is the application protocol that powers the Web. It began life as the so-called HTTP/0.9 protocol in 1991, and by 1999 had evolved to HTTP/1.1, which was standardised within the IETF (Internet Engineering Task Force). HTTP/1.1 was good enough for a long time but the ever changing needs of the Web called for a better suited protocol, and HTTP/2 emerged in 2015. More recently it was announced t
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
A Detailed Look at RFC 8446 (a.k.a. TLS 1.3)
A Detailed Look at RFC 8446 (a.k.a. TLS 1.3) Loading... For the last five years, the Internet Engineering Task Force (IETF), the standards body that defines internet protocols, has been working on standardizing the latest version of one of its most important security protocols: Transport Layer Security (TLS). TLS is used to secure the web (and much more!), providing encryption and ensuring the aut
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
Today we mitigated 1.1.1.1
On May 31, 2018 we had a 17 minute outage on our 1.1.1.1 resolver service; this was our doing and not the result of an attack. Cloudflare is protected from attacks by the Gatebot DDoS mitigation pipeline. Gatebot performs hundreds of mitigations a day, shielding our infrastructure and our customers from L3/L4 and L7 attacks. Here is a chart of a count of daily Gatebot actions this year: In the pas
Announcing 1.1.1.1: the fastest, privacy-first consumer DNS service
Announcing 1.1.1.1: the fastest, privacy-first consumer DNS service Loading... Cloudflare's mission is to help build a better Internet. We're excited today to take another step toward that mission with the launch of 1.1.1.1 — the Internet's fastest, privacy-first consumer DNS service. This post will talk a little about what that is and a lot about why we decided to do it. (If you're interested in
Why TLS 1.3 isn't in browsers yet
Upgrading a security protocol in an ecosystem as complex as the Internet is difficult. You need to update clients and servers and make sure everything in between continues to work correctly. The Internet is in the middle of such an upgrade right now. Transport Layer Security (TLS), the protocol that keeps web browsing confidential (and many people persist in calling SSL), is getting its first majo
Introducing Cloudflare Stream: Fixing the Streaming Video Market
Introducing Cloudflare Stream: Fixing the Streaming Video Market Loading... Cloudflare turns seven years old today. We launched on September 27, 2010. It was only a few days after our launch that we got our first request to support video streaming. Yet, until today, we'd avoided it. Why? Simply put: the video streaming market is screwed up. While there's a lot of money spent on video, there are on
