Availability class

Fleet-fatal · target 99.5%

Home internet connectivity for the entire home rack.

Class: tier-0 Fleet-fatal: loss stops the estate or risks data. Everything else waits.

RTO (achievable): —
RPO: —
State: none
Redundancy: single node
Failover: none
Failure domain: fd-home-rack

Health check: reachability probe every 300s — proves the home rack can reach the internet. Observed independently of the service.

Without it: The home rack is unreachable from outside and the private link is down. VIN and everything on it keeps serving; use VIN as the vantage point for triage.

Accepted risk: The class requires redundancy and there is none. isp-uplink

ISP Uplink is single-node but tier-0 requires a redundancy model.

Accepted by homelab-operator, review 2027-02-15: One circuit, no second uplink. A backup uplink is recurring cost against a zero-new-spend policy, and the estate is designed so that the edge node keeps serving during a home outage.
