QUIC is a secure low-latency transport layer protocol that is commonly known as the transport protocol of HTTP/3. Here, we’ll discuss how we added support for QLog, an incremental QUIC endpoint logging format, to H2O, an open- source HTTP server that we deploy throughout our edge cloud platform.

Low-latency live streaming is more relevant than ever. New user experiences, like quizzes and real-time voting, built around content and entertainment must be available with little to no delay. In this post, we look at the business cases that warrant low-latency HTTP live streaming.

As commerce companies embark on their digital transformation journeys, headless architecture is a hot topic. Here are five ways a modern CDN can deliver on the promise of headless commerce.

DDoS attacks have been growing larger over the past few years. But so has the industry’s response to them. In this post, we take a look at what industry bodies and a modern CDN can do to protect your traffic.

Ads leading up to the annual Black Friday - Cyber Monday holiday shopping weekend this year were remarkably devoid of the promises of “doorbuster” sales at the local malls and big-box stores. Instead, retailers moved their promotions to their ecommerce sites. With the weekend now in our rear-view mirror, we examine aggregate traffic volumes for 100 of Fastly’s top U.S. based ecommerce customers.

In this developer spotlight, we talk to Dora Militaru about her story and thoughts on the tech industry, as well as glean sage advice and inspiration for developers, hiring managers, and those with an unconventional story to share.

Layer 7 attacks that target applications and issue requests that can swamp origin systems often seek to blend into other network traffic and require a more focused defense than Layer 3 and 4 attacks. Here are five best practices you can implement to help prepare for such attacks.

Fastly Live Event Services helped power the Lexus Melbourne Cup, a 3-minute horse race that attracts millions of viewers across Australia. This year, the event saw more people live streaming than ever before and went off without a hitch.

Peak traffic is going to be on overdrive this year, and your ecommerce site needs to be prepared — but it’s not as hard as you might think. A good game plan should include these three best practices.

The largest category of difficult-to-anticipate security design weaknesses come from side-channel attacks. In this post, we take a tour of some of the more foundational and out-there side channel-related exploits that have afflicted the security conscious over the years.

QUIC and HTTP/3 have entered the final stages of development at the IETF. Distinguished Engineer, Jana Iyengar, elaborates on the current state of the protocols, their deployment across the internet, and his expectations for QUIC and HTTP/3 in the near future.

The Cache-Control response header is one of HTTP’s more widely known header fields; it allows a site to control how caches handle their data in CDNs, browsers, and elsewhere

The HTTP community has been busy modernizing the web’s protocol over the last decade, with multiple revisions of the core specification, a number of extensions, HTTP/2, and now HTTP/3. Unfortunately, the way we define and use HTTP header fields hasn’t changed much since the beginning, with underspecified headers (and lots of different ways to handle them) causing interoperability issues, developer pain, and even security problems. But help is coming.

Network error logging reports client-side failures and successes, enabling developers to understand how their sites function in the real world and how they might improve performance. In this post, we’ll explore the NEL framework, how it provides visibility, and ways to collect and process the resulting data.

Compare QUIC vs TCP to better understand the computational efficiency of both.

This series on the digital divide examines the data behind several yet-unexplored facets of the issue, the people and places it impacts most greatly, and what can and should be done to close this persistent gap.

HTTP/3 and QUIC aim to help the internet's so-called long-tail connections — connections that are most in need of improvement. What could that look like? For some, it could mean being able to actually use video calling and streaming media or even make a workable phone call. Let's look at the design principles that make these advancements possible.

How is COVID-19 affecting internet performance? We analyzed regional and vertical trends and found that, despite COVID-19-related traffic increases, the internet is up to the challenge.

These crucial pieces of internet architecture — only widely adopted over the last 10 years — are creating the capacity for us to live, work, and learn from home in unprecedented conditions.

The newest version of Transport Layer Security, TLS 1.3, is faster, more robust, and more responsive than ever before. Explore three ways it will help HTTPS protect origin names for improved confidentiality.
