Infrastructure notes

A small engineering practice: Linux servers, networking, monitoring and backup automation. We write down what we learn.

Keeping a monitoring log that people actually read

Alert fatigue is an operations problem, not a tooling problem. Short notes on thresholds, digests and quiet hours.

Backups: restore drills beat schedules

An untested backup is a hope. How we schedule restores, verify checksums and keep the runbook next to the archive.

TLS certificates without surprises

Renewal windows, SAN lists and why every certificate name should still resolve to the host that serves it.
