DDoS mitigation often relies on BGP for “scrubbing”, but how this appears in routing data is not well understood. We analyse five major providers to distinguish between always-on and on-demand protection.

 


This column argues that without AI, adequate privacy has become simply out of reach. This is not because AI is benign; it most definitely is not. Rather, the modern digital ecosystem has evolved to a point where no human, unaided, can understand, monitor, or manage the complexity of today’s data practices.

 


Conventional memory schemes follow the Pareto Principle, in which approximately maintaining 20% hot data can meet 80% of requests. L

 


Google has just forked its Tensor Processing Unit, or TPU, designs for these two workloads, the very first time in more than a decade that TPU systems of the same generation were truly architecturally distinct from each other.

 


Fake domains are not a new problem. What’s now changing is the scale and how easily attackers can blend into your domain ecosystem with lookalikes, inactive registrations, and domains set up purely for email.

The Linux 7.0 kernel is now out, and it’s one of the most impactful releases in years for networking professionals.

 


The human-speed defense of small business is being obliterated by the machine-speed offense of AI-driven cybercrime. Today, what large companies treat as a manageable risk is a terminal expense for small enterprises, with 60% of small enterprises shutting down within six months of a major attack.

 


The original frustration was familiar. You build on one provider, they change pricing, deprecate an API, or just aren’t the right tool anymore, and migrating is brutal.

Hedge 302: Communications in Biological Systems

What does biology have to do with computer networks? Much more than you might think. Communications systems, after all, need to solve the same problems–and they often use the same kinds of tools. In this episode of the Hedge, Emily Reeves and Joe Deweese join Russ and Tom to talk about a recent paper comparing computer communications to biological communications.

Industry analysts are using the word convergence as shorthand for competition that bundles cell service with broadband. Convergence is the newest strategy that replaces the traditional bundling strategy of selling a package of broadband, cable TV, and voice.

 


Leaving aside my discovery that YouTube videos on the Naturalistic Fallacy are branded by female cleavage (???), we move on to the two problems embedded in statements I hear by articulation and by implication in the public discourse: “We must cultivate trust in AI,” and “AI acquiescence is inevitable.”

 


Most engineers don’t think about securing TCP itself. We rely on the applications riding on top of the network. When you run routing protocols or long-lived control sessions across untrusted or shared infrastructure, TCP becomes part of your attack surface whether you planned for it or not.

Stanford researchers are warning that using AI chatbots for personal advice could backfire. The problem isn’t just accuracy, it’s how these systems respond when you’re dealing with complicated, real-world conflicts.

 


During the APNIC Routing Security Special Interest Group (SIG) session at APRICOT 2026 / APNIC 61, APNIC and LACNIC presented a case study of a Border Gateway Protocol (BGP) hijack that combined a technical attack with social engineering.

 


It is widely believed that all BGP routers within an Autonomous System (AS) must be connected in a full iBGP mesh, or, when this becomes impractical, that route reflectors or confederations must be used. However, a full mesh is not always necessary, and in some scenarios it may even be undesirable.

 


The skies are quickly filling with communications satellites. Following is a short list of the many ventures that have or will soon be launching large numbers of broadband satellites.

 


In early demos, the system looked impressive. It could summarize logs, explain configuration issues, and suggest possible fixes. Instead of digging through internal docs, the answers were coming back in seconds. For a while, it really felt like this system was going to work as expected.

However, eBPF has not seen similarly widespread adoption in other types of networked applications, such as web servers and databases. In this blog post, we argue that this gap stems from limitations in the current eBPF architecture — specifically, the kernel runtime, APIs, and compiler toolchain.

 


Time and again, I see people begging for companies with deep pockets to fund open source projects. I mean, after all, they’ve made billions from this code. You’d think they could support the code’s creators and maintainers. It would be only fair, right?

 


The weird, rare, surprising patterns that make data rich slowly get smoothed out when an AI model trains on outputs from a previous model.

 


In the previous note, the claim was not that the registry layer merely imposes visible fees or administrative inconvenience. The claim was more precise. The first extraction occurs when a scarce, transferable, revenue-enabling resource is kept institutionally discounted through non-asset rhetoric, conditional recognition, and friction around Continue reading
