A look at the network infrastructure for Electromagnetic Field, a 3500 capacity outdoor Hacker Camp in rural Herefordshire (2026 edition)
The DNSSEC KSK Key is rolling on Sunday. What this means and what might break.
Inside the very “center” of the internet is a set of networks run by companies who have a special arrangement with each other that the rest of us do not have, These are sometimes called the “tier ones” or “transit free networks”
However, are all of these “transit free networks” actually free of transit, and what does that actually mean?
In this talk will go over some of the bgp.tools data that I have been analyzing that will show have some of the T1 peering issues, where gaps exist, and how certain networks are getting closer to becoming a them, and what are the problems they will probably face, and finally does a network even want to be in this situation

A very quick demonstration of the Qubes OS, which brings virtualization to the desktop in a novel manner, and might be part of a solution for the puzzle of road warrior and/or productivity software while maintaining separation for TSA guidelines
This is a quick talk briefly discussing LINX’s experience of moving from having a couple of big, expensive OTDRs to giving all network engineers their own cheap pocket OTDR. Explaining how these are getting used on site and why everyone should have one.
I’ll also bring along my own pocket OTDR and some fibre for a bit of a hands on.

Ever wondered how you can see a correspondent live from the middle of nowhere, or embedded deep in a warzone? Let’s pull back the curtain on what goes into making live news. With a wide range of scenarios, and having to prepare for the absolute unknowns, I discuss how you plan, deploy and execute reporting from all kinds of scenarios.
Covering all kinds of connectivity from mobile networks to microwave links and satellite to dark fibre – challenging environments is what it’s all about.
How we did it and why*. Webcasting is a common thing now but it wasn’t always so easy to go live from anywhere. Even now anything more than your only fans stream still takes some work.

How swapping my home router broke my home automation and my wife’s investment app.
Unknown unicast on shared peering LANs is widely assumed to be transient. This case study presents the opposite: a self-perpetuating mechanism via RFC 4861 §7.3.1 forward-progress confirmation, where a single MAC change can leave a stale neighbour entry REACHABLE indefinitely while customer traffic — HTTPS SNI, signalling, residential 999 calls — is flooded to hundreds of member ports. A reproducible demonstration was published in November 2024. The talk presents the mechanism at the kernel and protocol level, a five-year timeline of reports and partial remediations at one IXP, the categories of disclosure and safety-of-life exposure at stake, and operational lessons for IXP operators and members. It closes on the speaker’s open self-examination: did I do enough on behalf of my customers?

Join us for an interactive session that showcases a Telecoms Security Act compliant uk-wide aggregation network which isolates both unicast and BUM traffic down to the switchport level by default with a minimum amount of per-service config, using a uniquely optimised mix of vendor-agnostic pure networking techniques from both the ISP and DC spaces.
A lot of the time we are building our network policy configuration out of the understanding that the underlying routing data we are being provided is not being tampered with, however how often is that actually true? How often does the path that is presented to us over BGP actually reflect the path that is measurable once we actually accept that route? In this presentation I will use the data that bgp.tools has on the wider internet routing table (IE the BGP control plane) and cross check that data against real world trace route data measurements to see how often the paths are misleading us, either maliciously or not.

A recent large scale DDoS attack against one of our customers revealed some problems with our exiting RTBH tooling. This talk aims to provide an insight into the problems with RTBH filtering from both sides of the table (as an IP Transit and DDoS protection provider, and as a customer/peer), and some ideas of what we as a community can do about it.
Small insight into DPDK, VPP and eBPF/XDP. How I started building a software based BNG with the goal of being able to serve IPoE and PPPoE subscribers and get up to multi-hundred gigabits of throughput, how I can move forward with getting the ISP community to try it out in labs and get to a production-grade BNG on x86 hardware

This session explores the real-world challenges and solutions of adopting multi-cloud networking at scale. We’ll cover how to integrate security seamlessly, automate operations across diverse environments, and build a foundation that balances agility, resilience, and control. Expect practical insights on connecting clouds, securing workloads, and simplifying operations for modern enterprises.
