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 and, if you are using an experimental browser those zones can be accessed using the new protocol! It's been great seeing so many people enable HTTP/3: having real websites accessible through HTTP/3 means browsers have more diverse properties to test against.
When we launched support for HTTP/3, we did so in partnership with Google, who simultaneously launched experimental support in Google Chrome. Since then, we've seen more browsers add experimental support: Firefox to their nightly builds, other Chromium-based browsers such as Opera and Microsoft Edge through the underlying Chrome browser engine, and Safari via their technology preview. We closely follow these developments and partner wherever we can help; having a large network with many sites that have HTTP/3 enabled gives browser implementers an excellent testbed against which to Continue reading
Jeff Tantsura published a great response to my Can We Trust BGP Next Hops blog post on LinkedIn, and I asked him for permission to save it in a more permanent form. Here it is (slightly edited)…
I’d like to bring back EVPN context. The discussion is more nuanced, the common non-arguable logic here - reachability != functionality.

Almost exactly two years ago, we launched Cloudflare Spectrum for our Enterprise customers. Today, we’re thrilled to extend DDoS protection and traffic acceleration with Spectrum for SSH, RDP, and Minecraft to our Pro and Business plan customers.
When we think of Cloudflare, a lot of the time we think about protecting and improving the performance of websites. But the Internet is so much more, ranging from gaming, to managing servers, to cryptocurrencies. How do we make sure these applications are secure and performant?
With Spectrum, you can put Cloudflare in front of your SSH, RDP and Minecraft services, protecting them from DDoS attacks and improving network performance. This allows you to protect the management of your servers, not just your website. Better yet, by leveraging the Cloudflare network you also get increased reliability and increased performance: lower latency!
Remote access to servers
While access to websites from home is incredibly important, being able to remotely manage your servers can be equally critical. Losing access to your infrastructure can be disastrous: people need to know their infrastructure is safe and connectivity is good and performant. Usually, server management is done through SSH (Linux or Unix based servers) and RDP (Windows based Continue reading
Take a Network Break! Grab a virtual donut, sit back and relax, and take a journey with us through Elysian fields of tech news analysis. We’ve got stories today on Cisco, VMware, a new PCAP appliance, a Tech Byte from sponsor Silver Peak with their SD-WAN customer C&S Wholesalers, and more.

Many networking solutions purport great Opex savings through automation, simulation and continuous integration. Similarly, there is a school of thought where network designs will have a single point in a network perform multiple roles. This will short change an initial Capex cost of purchasing additional switches with the intention of overlapping features on that single device.
Let’s take the simplest example. We have a 3 rack environment with dual-leaf per rack and 2 spines for inter-rack connectivity. In this design, we are leveraging VXLAN as the data plane overlay with BGP/EVPN as the control plane. Additionally, all 3 racks are compute, leaving no additional leafs to act as the service/border/exit leafs.
A network designer will look at the infrastructure and try to overlap features by repurposing the spines as exit leafs. Why will they think this way, you ask? Well, this is only an 8 switch design. Spending money on an additional 2 switches to act as dedicated border leafs uplifts my capex cost by 25 percent! I would then be required to buy 10 total switches instead of 8.
So instead, we end up overlaying the VXLAN onto the spines. So now the spines act as both interconnections between Continue reading
Last week, the U.S. Congress passed the third stimulus bill
in response to the COVID-19 pandemic. This bill primarily focused on economic
relief for companies, individuals, cities, states, and tribal communities. It
allocates over $2 trillion in funds for a variety of measures intended to ease
the burden of COVID-19.
Some of the included measures have been in the news for
weeks, including those related to individual checks for those financially
impacted by the virus. But there is an element to this bill that is equally
important, not only for our ability to cope with the virus now but also to
permanently change our country for the better.
These emergency funds allocate $150 billion to states and territories, including $8 billion specifically for Tribal governments, for “coronavirus relief.” What that relief looks like, however, is relatively vague. If a community was financially impacted by the pandemic between March and December of this year, in a way that they did not originally anticipate in their budgets, this fund covers most of those expenses.
And what is one of the biggest impacts we’ve seen? Millions
of people have been forced to isolate themselves at home and carry out their daily

Recently we have released a new Edge version 2.2.3.0 of Docker Desktop for Windows. This can be considered as a release candidate for the next Stable version that will officially support WSL 2. With Windows 10 version 2004 in sight we are giving the next version of Docker Desktop the final touches to give you the best experience running Linux containers on Windows 10.
One of the great benefits is that with the next update of Windows 10 we will also support running Docker Desktop on Windows 10 Home. We worked closely with Microsoft during the last few months to make Docker Desktop and WSL 2 fit together.
In this blog post we look behind the scenes at how we set up new WSL 2 capable test machines to run automated tests in our CI pipeline.
It started with a laptop
Let’s keep in mind that all automation somehow starts with manual steps and you evolve from there to get better and more automated. At the beginning of this project we were given a laptop back at KubeCon 2019 with an early version of WSL 2.
With that single laptop our development team could start getting their Continue reading
