About

Zeronodes is a small independent notebook about running services reliably with modest resources.

The notes here are written for people who look after a handful of servers and would rather understand the basics well than collect tools. There are no advertisements, no tracking and no accounts.

What you will find

• Explanations of how everyday internet plumbing works, such as DNS and TLS.
• Checklists for routine jobs like backups and certificate renewal.
• Occasional corrections when something written earlier turns out to be incomplete.

New notes appear a few times a year, when there is something worth saying.
