About

Iron Ladder is a personal notebook about operating small infrastructure: single-digit numbers of servers, one person on call, and a strong preference for things that are boring to run.

The name comes from the fixed iron ladders on old water towers — unglamorous, bolted on decades ago, and still the safest way up. That is roughly the standard I aim for.

What you will find here

• Post-mortems of my own mistakes, kept short
• Occasional measurements, with the method included so you can disagree

This site

Static HTML, one stylesheet, no trackers and no JavaScript. It is served by nginx from a small VPS. If something here is wrong or outdated, I would like to know.
