Chile takes the crown for fastest broadband in the OECD

A recent study by the UK-based price comparison site Uswitch has found that Chile boasts the fastest average broadband internet connection across the 37 member countries of the Organisation for Economic Cooperation and Development (OECD), followed by Denmark and the United States.At 189.36Mbps, the average Chilean broadband connection can download a 1,500MB movie in just over a minute – that’s about 100Mbps faster than the average connection across the OECD, and seven times faster than the slowest country, which was Turkey, clocking in at 26.34Mbps.The second- and third-slowest average broadband connections belonged to Greece and Mexico, at 33.41Mbps and 38.77Mbps, respectively. Denmark’s 163.60Mbps and the United States’ 143.76Mbps were good for second and third places at the top end, as mentioned.To read this article in full, please click here

Understanding Data Center Fabrics 05: Butterfly Scaling – Video

Episode of this series focuses on the butterfly fabric. While similar to a Clos fabric, the butterfly design is built around pods of switches. In this video, Russ White explains the differences in the butterfly design, physical limitations for ToR switches, how to scale the fabric to thousands of available ports without using chassis switches, […]

Ridiculously easy to use Tunnels

A little over a decade ago, Cloudflare launched at TechCrunch Disrupt. At the time, we talked about three core principles that differentiated Cloudflare from traditional security vendors: be more secure, more performant, and ridiculously easy to use. Ease of use is at the heart of every decision we make, and this is no different for Cloudflare Tunnel.

That’s why we’re thrilled to announce today that creating tunnels, which previously required up to 14 commands in the terminal, can now be accomplished in just three simple steps directly from the Zero Trust dashboard.

If you’ve heard enough, jump over to sign-up/teams to unplug your VPN and start building your private network with Cloudflare. If you’re interested in learning more about our motivations for this release and what we’re building next, keep scrolling.

Our connector

Cloudflare Tunnel is the easiest way to connect your infrastructure to Cloudflare, whether that be a local HTTP server, web services served by a Kubernetes cluster, or a private network segment. This connectivity is made possible through our lightweight, open-source connector, cloudflared. Our connector offers high-availability by design, creating four long-lived connections to two distinct data centers within Cloudflare’s network. This means that whether an individual Continue reading

2-Minute Linux Tips: How to use the date command

In this Linux tip, we’re going to look at using the date command to run tests. You can always use the date command to see what day it is, but you can also use it in scripts to test what time, day of the month or month of the year it is (and a lot of other things too).

Video: Managed SD-WAN Services

Should service providers offer managed SD-WAN services? According to Betteridge’s law of headlines, the answer is NO, and that’s exactly what I explained in a short video with the same name.

Turns out there’s not much to explain; even with my usual verbosity I was done in five minutes, so you might want to watch SD-WAN Technical Challenges as well.

What is the Spanning Tree Protocol?

The Spanning Tree Protocol, sometimes just referred to as Spanning Tree, is the Waze or MapQuest of modern Ethernet networks, directing traffic along the most efficient route based on real-time conditions.Based on an algorithm created by American computer scientist Radia Perlman while she was working for Digital Equipment Corporation (DEC) in 1985, the primary purpose of Spanning Tree is to prevent redundant links and the looping of communication pathways in complex network configurations. As a secondary function, Spanning Tree can route packets around trouble spots to ensure that communications are able to wind through networks that might be experiencing disruptions.To read this article in full, please click here

How to secure Kubernetes at the infrastructure level: 10 best practices

Infrastructure security is something that is important to get right so that attacks can be prevented—or, in the case of a successful attack—damage can be minimized. It is especially important in a Kubernetes environment because, by default, a large number of Kubernetes configurations are not secure.

Securing Kubernetes at the infrastructure level requires a combination of host hardening, cluster hardening, and network security.

• Host hardening – Secures the servers or virtual machines on which Kubernetes is hosted
• Cluster hardening – Secures Kubernetes’s control plane components
• Network security – Ensures secure integration of the cluster with surrounding infrastructure

Let’s dive into each of these and look at best practices for securing both self-hosted and managed Kubernetes clusters.

Host hardening

There are many techniques that can be used to ensure a secure host. Here are three best practices for host hardening.

Use a modern immutable Linux distribution

If you have the flexibility to choose an operating system (i.e. your organization doesn’t standardize on one operating system across all infrastructure), use a modern immutable Linux distribution, such as Flatcar Container Linux or Bottlerocket. This type of operating system is specifically designed for containers and offers several benefits, including:

• Immutability – This type Continue reading

What is Wi-Fi 6, and why do we need it?

Wi-Fi 6, also known as 802.11ax, was officially certified in 2020 and has quickly become the de facto standard for wireless LAN (WLAN), superseding Wi-Fi 5 (802.11ac). Wi-Fi 6 delivers improved performance, extended coverage, and longer battery life compared to Wi-Fi 5.Wi-Fi 6 was originally designed to address bandwidth problems associated with dense, high-traffic environments such as airports, stadiums, trains, and offices. However, the explosion of IoT devices that need to connect wirelessly to edge devices, and the ever-increasing bandwidth needs of new data-thirsty applications has rendered Wi-Fi 6 not exactly obsolete on arrival, but certainly not sufficient for some use cases.To read this article in full, please click here

How to build a high-speed network for the metaverse of things

How many people on social media have friends only in their home city? Probably not very many, so we shouldn’t think that when Meta or others deploy a metaverse, the inhabitants will all be drawn from the same place.To be successful, a metaverse has to support dispersed users, and the more successful it is, the more its users can be expected to be dispersed over a wider geography. Today, metro, but tomorrow the world. If, as the metaverse spreads out, latency issues destroy the synchronized behavior of the avatars, then it will lose realism and at some point that loss would constrain growth. We already know how to control access latency, but how do we control massive-metaverse latency? Answer: With Massive Metaverse Meshing.To read this article in full, please click here

Cloudflare Radar’s new ASN pages

An AS, or Autonomous System, is a group of routable IP prefixes belonging to a single entity, and is one of the key building blocks of the Internet. Internet providers, public clouds, governments, and other organizations have one or more ASes that they use to connect their users or systems to the rest of the Internet by advertising how to reach them.

Per AS traffic statistics and trends help when we need insight into unusual events, like Internet outages, infrastructure anomalies, targeted attacks, or any other changes from service providers.

Today, we are opening more of our data and launching the Cloudflare Radar pages for Autonomous Systems. When navigating to a country or region page on Cloudflare Radar you will see a list of five selected ASes for that country or region. But you shouldn’t feel limited to those, as you can deep dive into any AS by plugging its ASN (Autonomous System Number) into the Radar URL (https://radar.cloudflare.com/asn/<number>). We have excluded some statistical trends from ASes with small amounts of traffic as that data would be difficult to interpret.

The AS page is similar to the country page on Cloudflare Radar. You can find traffic levels, protocol Continue reading
