Field notes on running your own corner of the net.

akumu.network is a personal notebook about self-hosted infrastructure: small VPSes, home labs, wireguard meshes, DNS plumbing, and the occasional radio experiment. It is written mostly so that future-me remembers what past-me did at 2 a.m. — but it is public, because that is how the web was supposed to work.

There is no schedule, no newsletter and no tracking. New entries appear in notes whenever something took longer to fix than it should have. The about page explains what runs where.
