As said, I got bored last winter. Three friends with PI space, one switch, a /24 in a carrier hotel in Rotterdam. To be honest, it started as a joke.
- Switch: Edgecore AS4610-54T, 48x1G + 4x10G. €80 at auction.
- Cross-connect: €35/month per fiber pair.
- RIPE NCC fees for the ASNs: already sunk cost.
- Total monthly burn: €105 + power.
We peer over IPv4 and IPv6, no MLPA, no route servers. Just static configs, prefix lists, the usual. Throughput peaks at 340 Mbps during Steam updates. Latency between members: 0.2 ms.
Then the emails started. A regulator asked if we hold an ECN/telecom license. I explained: no paid transit, no resale, just three guys splitting rack space. Their reply: "not in scope." To be honest, I expected a fight.
The absurd part: one member now wants to add a fourth. At what point does "hobby" become "infrastructure"? I have no idea.
