Social Peering

The internet runs on trust before it runs on BGP. Two people who understood this better than anyone shaped everything I know about the NOG community — my mentor and his wife. "Social Peering" was Fearghas's word for it: the idea that every routing session is really a human handshake. This page exists because of them.

Fearghas McKay
15 Oct 1963 — 1 Oct 2025
Peering Evangelist · FLEXOPTIX GmbH
RIPE EIX Working Group Chair

Fearghas was my second father. He took me under his wing in the NOG world and taught me that the real protocol is trust — his own concept: "Social Peering." The belief that networks connect because people connect first. He built relationships across every continent, spoke at more than 25 NANOG conferences, chaired the RIPE EIX Working Group for fifteen years, and was one of the driving forces behind peering communities in Africa, Europe, and beyond. He was named an Africa Peering Champion. He was a RIPE Atlas Ambassador. But more than any title, he was the person in the room who made everyone feel like they belonged there — and he made me feel that too.

Susan Forney
25 Oct 1958 — 8 Sep 2021
Principal Network Engineer · NANOG Board
Hurricane Electric Internet Services

Susan was warmth and precision in equal measure. She became a network engineer in the 1990s at Boeing and Microsoft when almost no women worked in that role — and then spent decades making sure the next generation didn't have to fight the same battles. At Hurricane Electric she helped manage peering for AS6939, the world's largest IPv6 backbone. She served on the NANOG board, mentored engineers who would go on to run networks across the globe, and was — to me — like a second mother.

Erik Bais
— 28 May 2024
Founder A2B Internet · RIPE Address Policy WG Chair
Anti Abuse Network · Dutch Cloud Community

Erik was my mentor in the most personal sense. He taught me about living with ADHD and impulse control — not as something to be ashamed of, but as part of who I am. He showed me, by example, that every person deserves to be treated with dignity and equality, regardless of how their brain works or how the world has treated them. His NLNOG 2019 talk "Working in a Toxic Environment" changed how I see the tech community — and I carry that work forward in his name. A pillar of the RIPE community. Generous beyond measure. Always ready to help anyone who needed it.

"Fearghas was my second father — he showed me that the real protocol is trust, and that social peering is the foundation everything else runs on. Susan was warmth and strength, like a second mother to me. Erik taught me that I deserve to take up space in this world, that every person — regardless of how their brain is wired — deserves equal treatment and respect. They were my mentors. My family from across the wire. Every NOG I build tools for carries a piece of all three of them." — René Fichtmüller
