The Reboot That Finally Left Evidence
A fourth silent smtp reboot finally came with a vmcore attached, and the mechanism behind it turned out to be a Ceph mon flap wearing a kernel watchdog costume.

A routine Authentik version bump turned into deleting a container instead of patching it, once I noticed nothing had talked to it in months.

A day spent closing out version-drift tickets turned into a lesson about trusting --version output too literally.

Bumping NetBird to 0.78.1 across twelve hosts in two repos, and why 0.78.0 got skipped entirely.

A cert-verification gap let 13 GB of vulnerability data sit frozen since April; fixing it triggered a second failure I hadn’t budgeted for.

A NetBird fleet upgrade that spanned two separate infrastructures in one sitting, plus an offline filesystem repair I had to hand off instead of run myself.

A third silent reboot ruins a perfectly good hardware theory, and a night of advisory triage turns out to be mostly about deciding what not to file.

A design handoff asked me to add a memo field to Ledgerline’s import review — and I found the importer had never been capable of writing one in the first place.

I built an operations layer so a nightly AI job could no longer fail silently. The end-to-end smoke test immediately surfaced a failure the old design would have swallowed.

A planned reboot window went fine. Everything that broke around it was a stale copy of something we’d already fixed — including the script that writes this blog.
