The Key to (Not) Breaking the Internet: October’s Root KSK Rollover and Your Resolver
In October 2026, the DNSSEC root zone Key Signing Key will finally roll. For most end users this change should be invisible, but for anyone running validating recursive resolvers, misconfigured or stale trust anchors can turn October into the month when “the Internet breaks”. This talk will save you a long weekend at the office.
Tomaž Zaman, Mono
Tomaž Zaman grew up in central Slovenia in a family that ran an aluminum foundry, studied wood technology, and then discovered the web instead. In 2013 he co-founded Codeable, a marketplace connecting clients with WordPress experts that grew to more than 1,000 contractors serving 40,000 customers worldwide. After ten years he left to return to his hardware roots: frustrated with the state of modern routers (his YouTube channel tagline is simply “I hate routers”), he founded Mono and is building Gateway — a community-driven, open-source-first high-performance router (NXP Layerscape, dual 10G SFP+, OpenWrt). The first Gateway development kits have shipped and are in the hands of networking enthusiasts and reviewers around the world.

Out of memory: how AI ate my router’s RAM
Two years ago, building an open 10G router looked like a hardware problem: pick a good SoC, design the board, fight the SDK, ship. Nobody warned me that the hardest component to source in 2026 would be the most boring line on the BOM: RAM.
While the AI industry builds datacenters the size of small towns, memory manufacturers have quietly shifted their production capacity to feeding GPUs — and everyone else, from car makers to one-product hardware startups, is now bidding for what’s left. The result: DRAM contracts sold out years in advance, spot prices that change between two revisions of the same quote, and lead times that would embarrass a railway operator. My current favourite: an actual, serious offer, which went from $35 to $300 — in 6 months.
This is a progress report on Gateway, the open router we started building because none of this class existed: what shipped, what broke, what the community did with the dev kits — and what it’s like to run a small hardware company in a world where a chatbot’s appetite decides whether your product gets to have memory.

You can’t make everybody equally happy – Measuring anycast with an AI as the third member of a two-person team
6connect/ProVision operates an anycast DNS platform: six prefixes announced by 39 BGP nodes in 13 regions on five continents. For years we knew it worked — queries got answered — but we couldn’t prove how: who reaches which node, how fast, and where packets quietly die. Measuring anycast from the inside is a chicken-and-egg problem, because the network is explicitly designed to hide which instance you will hit.
This keynote tells two intertwined stories. The first is how we turned anycast’s most annoying property — ICMP replies landing on the “wrong” node — into our core measurement primitive, and grew it into a fully automated daily pipeline: 117,000 probes per second across 2.6 million targets, RTT/loss/jitter for 1.4 million addresses, PMTUD black-hole detection, ECMP traceroutes, BGP monitoring, and visibility measurements at 845 Internet Exchanges. The second story is how it was built: neither of us is a full-time developer. The system came out of an intensive pair-programming collaboration with AI coding models — reviewed by multiple independent models (Claude Opus 4.7/4.8, Google Gemini, Claude Fable 5), which kept finding real bugs. The AI did the heavy lifting; the humans supplied three decades of network intuition, direction, and veto power. The AI’s most-typed sentence in the project logs: “Your intuition was right.”

About the talk:
StratoWeave: a symphony of abstractions
Introducing StratoWeave – the open source platform for creating intent-based network orchestration systems. We will discuss the benefits of model-driven declarative transformations and integrated operational data collection, which are then used to build a closed-loop system that reacts to changes in the network. The examples used in the demo are based on a representative service provider network (MPLS Layer 3 VPN).

Case study: Building a Modern OT Network – Platform for OT (POT)
The POT project is one of the largest OT infrastructure modernization initiatives in Slovenia, supporting DARS, the national motorway operator. The project’s primary objective is to establish a resilient, secure, and centralized operational technology platform that enables reliable traffic management while addressing key business requirements, including IT/OT separation, cybersecurity, high availability, operational standardization, and long-term scalability.
This session will present the architecture, design principles, and implementation of a highly available transport network, modern data center infrastructure, and a secure OT environment. Special attention will be given to how the network architecture enforces IT/OT segmentation, improves operational resilience, and supports the migration of mission-critical traffic control systems without service interruption.
Presenters: Aleksander Kocelj (Head of IT at DARS), Luka Filipič (Internetworking specialist at NIL), Daniel Gutiérrez Rodríguez (SW Developer at NIL)
