If you advertise routes through a provider to the global Internet, you might be wondering if you should go through the trouble of registering in the RPKI and advertising ROAs. What is the tradeoff for the work involved in what seems like a complex process? Cecelia Testart joins Jeremy White and Russ White to discuss recent work in measuring the value of the RPKI.
To help developers build better web applications we researched and devised a fragments architecture to build micro-frontends using Cloudflare Workers that is lightning fast, cost-effective to develop and operate, and scales to the needs of the largest enterprise teams without compromising release velocity or user experience.
Here we share a technical overview and a proof of concept of this architecture.
One of the challenges of modern frontend web development is that applications are getting bigger and more complex. This is especially true for enterprise web applications supporting e-commerce, banking, insurance, travel, and other industries, where a unified user interface provides access to a large amount of functionality. In such projects it is common for many teams to collaborate to build a single web application. These monolithic web applications, usually built with JavaScript technologies like React, Angular, or Vue, span thousands, or even millions of lines of code.
When a monolithic JavaScript architecture is used with applications of this scale, the result is a slow and fragile user experience with low Lighthouse scores. Furthermore, collaborating development teams often struggle to maintain and evolve their parts of the application, as their fates are tied with fates of all the other Continue reading
Data visualization is the process of representing data in graphical or pictorial format. It helps to communicate complex information in a clear and concise way, allowing people to better understand the structure and meaning of data. Small businesses need data visualization solutions to gain valuable insights from their data, identify trends and patterns, make informed decisions and optimize processes.
The best data visualization software for small businesses can help to make sense of large amounts of data quickly and easily. These tools provide powerful visuals with interactive features and allow users to create custom dashboards that represent their data in an easy-to-understand format. Visuals created using these tools are also sharable, so multiple people can access the same information at the same time.
Canva is a great tool for small businesses. It offers an intuitive interface and a wide variety of templates that enable users to create custom visuals with just a few clicks. Canva’s drag-and-drop features make it easy to quickly build data visualizations, such as graphs, charts, tables, infographics and more.
Tableau is another popular data visualization tool. It enables users to create complex visuals with ease and provides an Continue reading
I’m always in a bit of a bind when I get an invitation to speak at a security conference (after all, I know just enough about security to make a fool of myself), but when the organizers of the DEEP Conference invited me to talk about Internet routing security I simply couldn’t resist – the topic is dear and near to my heart, and I planned to do a related webinar for a very long time.
Even better, that conference would have been my first on-site presentation since the COVID-19 craze started, and I love going to Dalmatia (where the conference is taking place). Alas, it was not meant to be – I came down with high fever just days before the conference and had to cancel the talk.

When you start a career you are inexperienced and somewhat immature, but also hungry for new experiences. Someone sees your potential and holds your hand, mentors you, and you appreciate it. But because you’re new, you think the final responsibility will be someone else’s. In short, you do not know what’s in store for you. […]

In 2018, we launched the Cloudflare Peering Portal, which allows network operators to see where your traffic is coming from and to identify the best possible places to interconnect with Cloudflare. We’re excited to announce that we’ve made it even easier to interconnect with Cloudflare through this portal by removing Cloudflare-specific logins and allowing users to request sessions in the portal itself!
We’re going to walk through the changes we’ve made to make peering easier, but before we do that, let’s talk a little about peering: what it is, why it’s important, and how Cloudflare is making peering easier.
Put succinctly, peering is the act of connecting two networks together. If networks are like towns, peering is the bridges, highways, and streets that connect the networks together. There are lots of different ways to connect networks together, but when networks connect, traffic between them flows to their destination faster. The reason for this is that peering reduces the number of Border Gateway Protocol (BGP) hops between networks.
For a quick refresher, Border Gateway Protocol (or BGP for short) is a protocol that propagates instructions on how networks should Continue reading
Here’s another question from the excellent list posted by Daniel Dib on Twitter:
BGP Split Horizon rule says “Don’t advertise IBGP-learned routes to another IBGP peer.” The purpose is to avoid loops because it’s assumed that all of IBGP peers will be on full mesh connectivity. What is the reason the BGP protocol designers made this assumption?
Time for another history lesson. BGP was designed in late 1980s (RFC 1105 was published in 1989) as a replacement for the original Exterior Gateway Protocol (EGP). In those days, the original hub-and-spoke Internet topology with NSFNET core was gradually replaced with a mesh of interconnections, and EGP couldn’t cope with that.
Whats the deal with Quiet Quitting ? Johna & Greg get into a heated debate about the nature of work. Johna wants people to ‘do your job’, Greg wants ‘pay me more to do more’. How much can a companies expect from their employees as hustle culture is being rejected by more people.

Cloudflare operates in more than 275 cities in over 100 countries, where we interconnect with over 10,000 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions. In many cases, these disruptions can be attributed to a physical event, while in other cases, they are due to an intentional government-directed shutdown. In this post, we review selected Internet disruptions observed by Cloudflare during the third quarter of 2022, supported by traffic graphs from Cloudflare Radar and other internal Cloudflare tools, and grouped by associated cause or common geography. The new Cloudflare Radar Outage Center provides additional information on these, and other historical, disruptions.
Unfortunately, for the last decade, governments around the world have turned to shutting down the Internet as a means of controlling or limiting communication among citizens and with the outside world. In the third quarter, this was an all too popular cause of observed disruptions, impacting countries and regions in Africa, the Middle East, Asia, and the Caribbean.
Companies are increasingly adopting managed Kubernetes services, such as Microsoft Azure Kubernetes Service (AKS), to build container-based applications. Leveraging a managed Kubernetes service is a quick and easy way to deploy an enterprise-grade Kubernetes cluster, offload mundane operations such as provisioning new nodes, upgrading the OS/Kubernetes, and scaling resources according to business needs.
AKS also provides a fault-tolerant Kubernetes control plane endpoint and automates the worker node maintenance and deployment process. With regards to networking within the cluster, AKS provides an integrated CNI to address basic Kubernetes networking requirements, such as configuring network interfaces and providing connectivity between pods. However, the basic container networking in Microsoft AKS comes with a limited set of IP addresses. As businesses grow, so does application usage. Having a limited set of IPs can cause scale, availability, and manageability challenges for Microsoft AKS users.
In this blog post, I will discuss IP address exhaustion on Microsoft AKS and how Calico can solve this issue. I will also explore how Calico can address scalability challenges and provide resources that can quickstart your journey in using Calico to solve IP address exhaustion on AKS.
Earlier this year, Microsoft AKS introduced the ability to bring Continue reading
