When the Internet Society, Asian Development Bank, and the United Nations Economic and Social Commission for Asia and the Pacific examined the regional digital economy of Central Asia in 2015, it recommended investing in the development of Carrier-Neutral Internet Exchange Points (IXPs) to drive down connectivity costs and enable more people to connect on the […]

Customers choose Cloudflare for our network performance, privacy and security. Cloudflare Network Interconnect is the best on-ramp for our customers to utilize our diverse product suite. In the past, we’ve talked about Cloudflare’s physical footprint in over 200+ data centers, and how Cloudflare Network Interconnect enabled companies in those data centers to connect securely to Cloudflare’s network. Today, Cloudflare is excited to announce expanded partnerships that allows customers to connect to Cloudflare from their own Layer 2 service fabric. There are now over 1,600 locations where enterprise security and network professionals have the option to connect to Cloudflare securely and privately from their existing fabric.
Since we launched Cloudflare Network Interconnect (CNI) in August 2020, we’ve been focused on extending the availability of Cloudflare’s network to as many places as possible. The initial launch opened up 150 physical locations alongside 25 global partner locations. During Security Week this year, we grew that availability by adding data center partners to our CNI Partner Program. Today, we are adding even more connectivity options by expanding Cloudflare availability to all of our partners’ locations, as well as welcoming CoreSite Open Cloud Exchange (OCX) and Infiny by Epsilon Continue reading

Here is another post of the series on basic network troubleshooting and tools under Linux. In this post, I will talk about tcpdump. Other posts of the series This post is part of a series of basic Linux Networking tips and tricks. The other posts of this series are: The ip and nmcli commands The mtr command The ss and netstat commands The curl command tcpdump Introduction I think the most essential element to debug a network problem is a packet capture tool or sniffer, and the most common one…

In June 2020, a friend of mine asked me to do a short presentation on lessons learned during my 35 years of being a networking engineer. It went reasonably well, so I decided to turn it into a webinar, starting with regardless of what the disruptive marketers tell you, technology still matters.

Calico is the industry standard for Kubernetes networking and security. It offers a proven platform for your workloads across a huge range of environments, including cloud, hybrid, and on-premises.
Given this incredibly wide support, why did we decide to create a course specifically about AWS?
Well, our previous online course continues to be a great success (it’s self-paced, so if you haven’t already, we would love for you to take it and become an expert in Kubernetes networking and security). The course covers how Kubernetes networking works, how to configure and manage a Calico network, and how to secure your Kubernetes cluster.
Once you know the underlying concepts, it becomes a more important consideration to identify the nuanced differences between possible implementations. These become even more relevant once you have selected a platform to move forward with.
Amazon’s cloud computing platform, AWS, has played a huge role in changing the landscape around how users consume compute resources and data. As little as ten years ago, it would have been difficult to anticipate the speed with which companies and other organizations would embrace moving their precious compute resources and data out of their Continue reading
Starting today, you can build identity-aware, Zero Trust network policies using Cloudflare for Teams. You can apply these rules to connections bound for the public Internet or for traffic inside a private network running on Cloudflare. These rules are enforced in Cloudflare’s network of data centers in over 200 cities around the world, giving your team comprehensive network filtering and logging, wherever your users work, without slowing them down.
Last week, my teammate Pete’s blog post described the release of network-based policies in Cloudflare for Teams. Your team can now keep users safe from threats by limiting the ports and IPs that devices in your fleet can reach. With that release, security teams can now replace even more security appliances with Cloudflare’s network.
We’re excited to help your team replace that hardware, but we also know that those legacy network firewalls were used to keep private data and applications safe in a castle-and-moat model. You can now use Cloudflare for Teams to upgrade to a Zero Trust networking model instead, with a private network running on Cloudflare and rules based on identity, not IP address.
To learn how, keep reading or watch the demo below.

The Internet Society and the Asia Pacific Internet Exchange Association (APIX) commit to work together to support communities that build the Internet and improve digital infrastructure in the region. At the peak of the COVID-19 pandemic, average international Internet traffic increased by 48%, putting an unprecedented strain on the Internet. The trend was the same […]

WebP and AVIF are two image formats for the web. They aim to produce smaller files than JPEG and PNG. They both support lossy and lossless compression, as well as alpha transparency. WebP was developed by Google and is a derivative of the VP8 video format.1 It is supported on most browsers. AVIF is using the newer AV1 video format to achieve better results. It is supported by Chromium-based browsers and has experimental support for Firefox.2
Your browser supports WebP and AVIF image formats. Your browser supports none of these image formats. Your browser only supports the WebP image format. Your browser only supports the AVIF image format.
Without JavaScript, I can’t tell what your browser supports.
For this blog, I am using the following shell snippets to convert and optimize JPEG and PNG images. Skip to the next section if you are only interested in the Nginx setup.
JPEG images are converted to WebP using cwebp.
find media/images -type f -name '*.jpg' -print0 \ | xargs -0n1 -P$(nproc) -i \ cwebp -q 84 -af '{}' -o '{}'.webp
