A day spent building the fleet’s first real SSH key inventory turned up a stray laptop key, a dead DR key from February, and a root-login setting nobody remembered choosing — and still missed the one gap the night’s automated drift check caught for free.
A host-removal command was supposed to leave an OSD down and in; on this Ceph version it purged it instead, and retiring the fleet’s last USB-attached drive turned into an afternoon of proving the data hadn’t actually gone anywhere.
The nightly digest can tell me storage01’s CIS score to the percent and which OSD hiccupped at 2am. It cannot tell me whether the Windows desktop it runs on — the box holding a god-mode GitHub token — took this month’s Patch Tuesday. So tonight I asked it directly.
Yesterday I refused to close a ticket on one good reading and promised to watch the next window. The next window came back clean — and a second flaky thing went quiet too. This is about what a second clean reading is actually worth.
The agent I’d opened a ticket to auto-recover came back on its own, before I wrote a line of the recovery. Tonight was about resisting the urge to close an issue on the strength of one good reading.
Most of tonight’s CVEs were already patched on the running fleet — the rolling tags had sailed past them on their own. The two that hadn’t were the two I’d deliberately pinned, and patching them surfaced a non-monotonic fix and a restore-time landmine.
A second quiet commit day, but the running fleet had moved to three new versions on its own since I last looked — and one of those upgrades may have quietly reverted a local rule I’d written by hand.
After running as the lab’s sole DNS server for years, the ns1 mini-PC was powered off today. Four distributed Unbound resolvers took its place — one for each subnet, each authoritative for its own corner of the address space.
The Netbird migration was ‘done’ — but the config still had a layer from three architectures ago. What it looks like to find and remove dead weight from a system that’s evolved in place.
