Hi all,

SwiNOG #41, held on April 28, 2026, on Bern’s Gurten, once again demonstrated what makes the Swiss Network Operators Group special: strong technical content, an engaged community, and a format that simply works.

This edition saw exceptionally high demand — for the first time, we had to introduce a waiting list. Out of 180 available seats, 169 participants joined on the day, reflecting a consistently strong show rate and the commitment of the community.

Technical depth that matters

The agenda covered a wide range of real-world challenges and forward-looking topics. From optical transport insights — such as analysing transceiver efficiency using VDM metrics — to practical approaches in network automation, observability, Agentic Network Operations: What AI Can (and Can’t) Do in and infrastructure resilience, the talks stayed close to what operators actually deal with day-to-day.

What stood out again was the balance: no buzzword bingo, no vendor fluff — just technical talks, shared experiences, and things you can actually take back and apply.

This ensures the content lives beyond the event and remains accessible to the broader community.

Looking ahead

SwiNOG continues to grow — not just in numbers, but in relevance. The increasing demand shows that there is still a strong need for a neutral, community-driven space focused on real technical exchange.

A big thank you to all speakers, sponsors, and participants who made SwiNOG #41 possible.

See you at the next one. SwiNOG #42 is in the planning for this autumn.
