Notes from people who carry the pager.

CharmNode started as a set of internal notes for a small crew of infrastructure operators who got tired of explaining the same lessons to every new hire. Running a node isn't hard to start. It's easy to run badly for months without noticing, and most of the writing available online is either a sales page for hardware or a forum thread that assumes you already know the vocabulary.

Who this is for

We write for the gap in between: people who've got a node running, or are about to, and want to do it the way someone with years of pager duty actually would. Uptime discipline. Key hygiene. Patch cadence that doesn't turn into a Saturday emergency. The kind of operational habits that don't make it into a quick-start guide because they're not exciting enough for one.

What to expect

Nothing here is sponsored by a hardware vendor or a staking service, and we're not chasing a course to sell you afterward. If a field note stops being useful, we'll say so and move on to the next one. Expect plain language, real trade-offs instead of hype, and the same respect for your time that we'd want from anyone writing about our own infrastructure.
