On the 11th of January 1982 twenty-two computer scientists met to discuss an issue with ‘computer mail’ (now known as email). Attendees included the guy who would create Sun Microsystems, the guy who made Zork, the NTP guy, and the guy who convinced the government to pay for Unix. The problem was simple: there were 455 hosts on the ARPANET and the situation was getting out of control. This issue w

The new wave of Javascript web frameworksMake sense of the proliferation of new Javascript web frameworks. A deep dive into the problems at scale and the recent evolution of innovation.

It’s challenging for those entering the industry to follow what’s happening amongst the new libraries, frameworks, concepts, an
We announced support for HTTP/3, the successor to HTTP/2 during Cloudflare’s birthday week last year. Our goal is and has always been to help build a better Internet. Collaborating on standards is a big part of that, and we're very fortunate to do that here. Even though HTTP/3 is still in draft status, we've seen a lot of interest from our users. So far, over 113,000 zones have activated HTTP/3 an

How Docker Desktop Networking Works Under the Hood | Docker
Modern applications make extensive use of networks. At build time it’s common to apt-get/dnf/yum/apk install a package from a Linux distribution’s package repository. At runtime an application may wish to connect() to an internal postgres or mysql database to persist some state, while also calling listen() and accept() to expose APIs and UIs over TCP and UDP ports. Meanwhile developers need to be

SAD DNS Explained
This week, at the ACM CCS 2020 conference, researchers from UC Riverside and Tsinghua University announced a new attack against the Domain Name System (DNS) called SAD DNS (Side channel AttackeD DNS). This attack leverages recent features of the networking stack in modern operating systems (like Linux) to allow attackers to revive a classic attack category: DNS cache poisoning. As part of a coordi

Why your website should be under 14kB in size | endtimes.dev
Having a smaller website makes it load faster — that's not surprising. What is surprising is that a 14kB page can load much faster than a 15kB page — maybe 612ms faster — while the difference between a 15kB and a 16kB page is trivial. This is because of the TCP slow start algorithm. This article will cover what that is, how it works, and why you should care. But first we'll quickly go over some of

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

UPDATE: To continue our support of this public NTP service, we have open-sourced our collection of NTP libraries on GitHub.

Many clocks contain inaccurate internal oscillators, which can cause seconds of inaccuracy per day and need to be periodically c
An Engineer's Hype-Free Observations on Web3 (and its Possibilities)
The Web3 ecosystem has been variously described as a collective hallucination, a massive grift, an environmental disaster, a decentralized renaissance, and the future of the Internet. That’s a lot to live up (and down) to. Here in the PSL Studio, our veteran engineering team (hi, nice to meet you!) has been building fun new Web3 projects. Along the way, we’ve been taking notes on what we’ve learne

I first learned Kubernetes ("k8s" for short) in 2018, when my manager sat me down and said "Cloudflare is migrating to Kubernetes, and you're handling our team's migration." This was slightly terrifying to me, because I was a good programmer and a mediocre engineer. I knew how to write code, but I didn't know how to deploy it, or monitor it in production. My computer science degree had taught me a
How Does BlueSky Work?
Home Blog 2024-02-24 One of the reasons I am enthusiastic about BlueSky is because of the way that it works. So in this post, I am going to lay out some of the design and the principles behind this design, as I understand them. I am not on the BlueSky team, so these are my takes only. Let’s begin. Why does BlueSky exist? Here’s what the BlueSky Website says right now: Social media is too important
Wait! You also have to make a call to WSAStartup() before doing anything else with the sockets library. You pass in the Winsock version you desire to this function (e.g. version 2.2). And then you can check the result to make sure that version is available. The code to do that looks something like this: #include <winsock2.h> { WSADATA wsaData; if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0) { fprin

As the scale of Cloudflare’s edge network has grown, we sometimes reach the limits of parts of our architecture.
