I built this cluster to keep production ISP services online through failures and planned maintenance. The design centered on service continuity, not just hardware utilization.

Linux-based failover tooling and replicated storage gave the provider a more durable platform for critical network services, which reduced downtime risk in a business that depended on constant availability.
