  • Prevent attacks with proof of work | Fastly

    Andrew Betts

    With attackers using publicly available lists of compromised passwords in an attempt to steal accounts, proof of work is a good way to slow the attackers down.

  • Fastly’s Initial Public Commit

    Artur Bergman

    Today, we listed on the New York Stock Exchange, marking our first day of trading as a public company. Our IPO is a big milestone for Fastly, as well as a celebration of the collective success of our global community and customers. I am so proud of what we’ve built together — and this is just the beginning.

  • The lifecycle and performance of a Lucet instance

    Adam Foltzer

    Lucet, Fastly’s open source WebAssembly compiler and runtime system, is designed to take WebAssembly beyond the browser, and build a platform for faster, safer execution on Fastly’s edge cloud. This post will introduce each step in the Lucet lifecycle, and benchmark its performance to highlight how we keep overhead low.

  • Expanding Fastly’s Partnership with Microsoft Azure | Fastly

    Marcus Sarmento

    We believe that developers should have the freedom to choose the best possible solution for their needs — without worrying about unpredictable costs. The internet should be a great experience for you and your team regardless of what platforms you use to digitally transform your business. That’s why we’re partnering with Microsoft Azure to offer cost-effective data transfer to our joint customers. Starting today, any outbound data transfer between select Azure regions and Fastly POPs will be highly available, and data transfer costs will be covered by Fastly through our agreement with Microsoft.

  • Feature policy: the web's missing guardrails

    Andrew Betts

    Over almost 30 years of its life, the web has grown beyond anyone's imagination, and the platform has become immensely powerful and flexible. With that power and flexibility comes complexity, and the potential for slow or insecure websites to deliver a poor user experience that drives people away from the web. Feature policy is here to help, and we've built a tool to show you how to use it.

  • Lucet Takes WebAssembly Beyond the Browser | Fastly

    Pat Hickey

    Today, we're thrilled to announce the open sourcing of Lucet, our native WebAssembly compiler and runtime. WebAssembly is a technology created to enable web browsers to safely execute programs at near-native speeds, and it's been shipping in the four major browsers since early 2017.

  • Supercharging Server Timing with HTTP trailers

    Hooman Beheshti, Dragana Damjanovic

    Server Timing is a great mechanism for collecting new performance metrics in the browser. Fastly and Firefox have teamed up to make them even more powerful by adding support for using Server Timing with HTTP trailers.

  • Why Fastly loves QUIC and HTTP/3

    Jana Iyengar

    We're thrilled to be so invested in QUIC, a new transport protocol that is more responsive, secure, and flexible than what the internet uses today. Learn why, straight from our very own Jana Iyengar, one of the editors of the core document.

  • New branding, same mission

    Rachel Goldberg

    We are building a more trustworthy internet: where developers can innovate faster, so good companies can do great things. To better capture that spirit, we’ve refreshed our branding.

  • Creating standards for CDNs

    Mark Nottingham

    Content delivery networks (CDNs) have been around for a long time, but they’re not all built in the same way. While Fastly’s edge cloud platform goes beyond traditional content delivery networks by moving things to the edge, there are more fundamental differences; it’s not uncommon for CDNs to make up their own rules about how they serve web traffic, since CDNs didn’t exist when HTTP was defined. To improve this, we’re working alongside other platforms to standardize basic protocol handling for CDNs.

  • Guide for C and Rust programmers

    Frank Denis

    Recently we launched Fastly Terrarium, a multi-language, browser-based editor and deployment platform where you can experiment with edge technology. Now, for those well-versed in C and Rust, we'll explore WebAssembly memory management and implementation.

  • How experimentation accelerates digital transformation

    Rachel Goldberg

    Experimentation goes beyond launching new features, to embodying a shift in technology, processes, and attitude. Learn how Reddit and The New York Times embraced experimentation to exceed their goals and continue their digital evolution.

  • Unicode in VCL

    Katherine Flavel

    There's more to life than just the Latin alphabet. Because we’re a global platform with humans using all kinds of writing systems, recently we added the ability to write synthetic responses — e.g. a web page with an error message — in UTF-8 in Fastly VCL. In this post, Engineering Director Katherine Flavel shares some of the behind-the-scenes work to show how we did that.

  • Improve response, drive digital change | Fastly

    Rachel Goldberg

    The ability to get real-time data for your site or app, respond quickly, and see your changes reflected in real-time is crucial for businesses today. See the ways in which companies like HotelTonight and Gannett/USA Today have boosted their responsiveness, and freed up their teams to innovate.
