Every bug I hit while building my own VPN gateway, internal network and DNS, grouped by kind, with the symptom, the cause and the fix, and the three patterns behind most of them.
Why I split DNS into two layers, CoreDNS as the authority for my internal names and Pi-hole as the filtering resolver my devices use, and the settings that keep internal names from leaking.
Deploying the voice agent on Kubernetes: why one missing webhook secret took a whole namespace down three times, the split-horizon DNS that silently killed observability, and the isolation patterns that came out of it.
