# Day-2 operations

> Reassigning nodes, offline handling, demo mode, and the drills behind the reliability claims.

## Reassign a node

Between your tenants, or back to your capacity pool, from the node's detail
page. Customers release their own rented nodes too.

* Attribution flips **atomically**.
* Historical data **keeps its original tenant** — documented, never rewritten.
* A node never leaves your operator: there is no destination outside it.

## Offline nodes

Flagged in the UI after **2 missed minutes** of heartbeats, with a banner
listing them.

Agents self-heal: fix the network and telemetry backfills itself, with original
timestamps, up to the 55-minute replay cap.

## Demo mode

A simulated fleet can be run against the live console for sales demos.
Everything simulated is badged **SIMULATED** in both the data and the UI.

Real telemetry is never mixed with it silently:

* Simulated machines are **hidden from every dashboard by default**.
* They appear only for accounts that switch **Show simulated data** on in the
  profile menu.
* Any view that hid something **says how many it hid** — so an empty dashboard
  is never ambiguous.

## Operational rehearsals

These are rehearsed rather than assumed, and recorded with results in the
operator runbook:

| Drill                 | What it proves                                              |
| --------------------- | ----------------------------------------------------------- |
| Agent `kill -9`       | The node is unaffected and telemetry resumes                |
| 10-minute network cut | Buffer and capped backfill behave as documented             |
| Credential rotation   | Identity federation rotates without downtime                |
| Deploy rollback       | A bad release can be reverted immediately                   |
| Backup restore        | Point-in-time recovery and nightly exports actually restore |

<Note>
  If you run a sovereign or on-prem deployment, these drills are yours to run on
  your schedule. The runbook has the procedures and the recorded results from
  ours. [Ask us for it](mailto:charles@usechamber.com).
