From system of record to system of control: How NetBox Labs is making network engineers “masters of intent.”

Early internet networks were small enough that a single engineer could hold the entire system in their head. You didn’t need a system of record — you were the system of record. As networks expanded into the cloud, that model broke down. Infrastructure now sprawls across regions, providers, and services. The live state of the network became both impossible to understand and critical to get right fully. Network infrastructure is now the backbone of the business, and configuration errors are no longer nuisances; they are business-critical events. AI agents are further pressuring network infrastructure to the extreme — so how are network engineers to keep it all running flawlessly? Bespoke tracking doesn’t scale Excel spreadsheets and cloud dashboards are no longer going to cut it. Running modern infrastructure requires a reliable representation of what the network should be — what systems and services exist, where they live, and how they connect. Without that, managing the network becomes high-risk. In the past, your mapping might have fit into an Excel spreadsheet, and everything could be configured in the terminal. But today’s networks need more than a wizard at the terminal; they need architects who can look at the big picture and Continue reading

Shutdowns, power outages, and conflict: a review of Q1 2026 Internet disruptions

In the first quarter of 2026, government-directed shutdowns figured prominently, with prolonged Internet blackouts in both Uganda and Iran, a stark contrast to the lack of observed government-directed shutdowns in the same quarter a year prior. This quarter, we also observed a number of Internet disruptions caused by power outages, including three separate collapses of Cuba's national electrical grid. Military action continued to disrupt connectivity in Ukraine and also impacted hyperscaler cloud infrastructure in the Middle East. Severe weather knocked out Internet connectivity in Portugal, while cable damage disrupted connectivity in the Republic of Congo. A technical problem hit Verizon Wireless in the United States, and unknown issues briefly disrupted connectivity for customers of providers in Guinea and the United Kingdom.

This post is intended as a summary overview of observed and confirmed disruptions and is not an exhaustive or complete list of issues that have occurred during the quarter. A larger list of detected traffic anomalies is available in the Cloudflare Radar Outage Center. Note that both bytes-based and request-based traffic graphs are used within this post to illustrate the impact of the observed disruptions, with the choice of metric generally made based on which better illustrates the Continue reading

NB572: Quantum Switches and Flying Cars

Take a Network Break! We start with follow up on Anthropic’s Project Glasswing and Linux 7.0. On the news side, Cisco announces a prototype quantum switch that promises to support multiple quantum encoding modalities, Cato Networks adds an enterprise browser to its security offerings, and Mozilla validates the bug-finding powers of Anthropic’s Mythos model.

You Can’t Patch People

One of the things I’ve noticed when it comes to IT is how quickly we’re willing to use software to solve people problems. Over my career I’ve seen all manner of crazy solutions to get around people being lazy or uneducated. Remember vMotion? Or OTV for stretched layer 2? Why do you think those solutions came about? I posit that it’s because it’s faster to write software than to patch people.

Hacking Humans

I see this most often in cybersecurity. Developers love to create software solutions that prevent things from happening. Phishing and all its various forms are some of the top priorities for solutions that prevent leaking of information. While we have invested a lot in phishing tests and education it’s also very likely that there are controls in place that prevent users from accidentally giving out information to threat actors.

Why are we so willing to write software to fix problems instead of teaching people to avoid those issues? I think in part it’s because software is predictable. If I create an app or write some controls into a platform it’s going to behave the same way every time. That’s the definition of deterministic. Every time the software Continue reading

HN824: That’s Not a Job for an LLM: The Right Way to Apply AI to Network Operations (Sponsored)

On today’s sponsored Heavy Networking, we get off the AI hype train to talk about how different artificial intelligence techniques usefully impact network operations—and where they aren’t a fit. The various forms of AI represent a set of tools that, like any tool, have use cases, capabilities, and limitations. Our guest is Avi Freedman, CEO... Read more »

State of Network Automation with Urs Baumann

I stopped tracking the (lack of) progress in network automation years ago, when I realized I had nothing new to say. As an eternal optimist, I hoped I was just missing something, but Urs Baumann (the guest of Software Gone Wild Episode 206) destroyed my hopes when he said, “I can still use the same slides I created 10 years ago”. On a more positive note, he recently completed his Master’s thesis on AI in network engineering, so we ended with a nice chat on its potential impact.
