A small infrastructure journal
Notes on running a handful of quiet services — what broke, what got fixed, and what got left alone on purpose.
Recent
Entries are irregular. Most start as a debugging session and get tidied up once the fire is out.
DNS TTLs
Why a low TTL saved a migration weekend.
Disk quotas
The service that quietly filled a volume over a month.
Cron drift
Two timers, one job, and a race nobody noticed for weeks.
Alert fatigue
Cutting alerts from forty a day down to three that matter.
Conventions
- Every service has an owner, even the small ones.
- Nothing ships without a rollback path.
- Logs are for humans first, machines second.
- If it paged twice for the same reason, it gets fixed, not silenced.
