Video: Rogue IPv6 RA Challenges
IPv6 security-focused presentations were usually an awesome opportunity to lean back and enjoy another round of whack-a-mole, often starting with an attacker using IPv6 Router Advertisements to divert traffic (see also: getting bored at Brussels airport) .
Rogue IPv6 RA challenges and the corresponding countermeasures are thus a mandatory part of any IPv6 security training, and Christopher Werny did a great job describing them in IPv6 security webinar.

Key advantages of the Calico eBPF data plane
Project Calico and eBPF
Project Calico has offered a production-ready data plane based on eBPF since September 2020, and it’s been available for technical evaluation for even longer (since February 2020).
The pre-requisites and limitations are simple to review, it’s easy to enable, and it’s easy to validate your configuration. So, there’s never been a better time to start experiencing the benefits!
You do know what those are, don’t you? Don’t worry if not! That’s what this blog post is about. We’ve reached a point where the journey is easy to make, if you know why you want to get there.
Key advantages of using Calico with eBPF
Calico is already the most widely deployed Kubernetes network security solution. What can eBPF do to help our winning formula further? I’ll dive into the details, but let’s look at the highest possible level first.
These three key benefits apply across all supported environments:
- General performance
- Native Kubernetes service handling
- Source IP preservation and Direct Server Return, or DSR
- Each of these benefits is significant and worth discussing in more detail.
Performance
Calico’s eBPF data plane achieves high performance in several ways. Firstly, it achieves higher throughput and/or less CPU Continue reading
How Queen Elizabeth II’s Platinum Jubilee had an impact on the Internet
“I declare before you all that my whole life, whether it be long or short, shall be devoted to your service and the service of our great imperial family to which we all belong.”
— Queen Elizabeth II birthday speech, April 21, 1947
The rising and setting of the sun has an impact on human behaviour and on Internet trends, and events like this weekend's celebration of Queen Elizabeth II’s Platinum Jubilee also show up in Internet trends.
When Elizabeth II's reign started, on February 6, 1952 (the coronation was on June 2, 1953), the Turing machine had already been proposed (1936), and with that the basis for computer science. ARPANET, which became the technical foundation of the Internet, was still a dream that came to fruition in the late 60s — the World Wide Web is from 1989 and in 2014 we celebrated its Silver Jubilee. So, with that in mind, let’s answer the question: did the 2022 celebrations of the first British monarch with a 70th anniversary on the throne have an impact on the UK’s Internet traffic?
First, some details about the Platinum Jubilee. There was a four-day bank holiday (June 2-5) in the UK Continue reading

A new portal for Project Galileo participants
This post is also available in 日本語, Deutsch, Français, Español and Português.
Each anniversary of Project Galileo serves as an impetus for big-picture thinking among the Cloudflare team about where to take the initiative next. For this eighth anniversary, we want to help participants get the most out of their free security and performance services and simplify the onboarding process.
Organizations protected under Galileo are a diverse bunch, with 111 countries represented across 1,900+ web domains. Some of these organizations are very small and sometimes operated solely by volunteers. It is understandable that many do not have IT specialists or other employees with technical knowledge about security and performance capabilities. We strive to give them the tools and training to succeed, and we felt it was imperative to take this effort to a new level.
Introducing the Cloudflare Social Impact Projects Portal
To provide Galileo participants with one place to access resources, configuration tips, product explainers, and more, we built the Cloudflare Social Impact Projects Portal.
The crisis in Ukraine was a key source of inspiration for this endeavor. With overall applications for the project skyrocketing by 177% in March 2022, we were rushing to onboard new Continue reading

Using Custom Vagrant Boxes with netsim-tools
A friend of mine started using Vagrant with libvirt years ago (it was his enthusiasm that piqued my interest in this particular setup, eventually resulting in netsim-tools). Not surprisingly, he’s built Vagrant boxes for any device he ever encountered, created quite a collection that way, and would like to use them with netsim-tools.
While I didn’t think about this particular use case when programming the netsim-tools virtualization provider interface, I decided very early on that:
- Everything worth changing will be specified in the system defaults
- You will be able to change system defaults in topology file or user defaults.
