Hardware failures are inevitable—but outages are not, if redundancy is properly built into your network. In this episode, we focus on how to create fault-tolerant infrastructure through redundant routers, switches, and physical links. We explore concepts like dual-homing, redundant power supplies, cooling backups, and battery-based UPS systems. You’ll also learn how to assess single points of failure and plan for seamless failover during maintenance or emergencies.

Beyond networking gear, we examine facility-level concerns such as redundant HVAC, generators, and structured cabling. These physical layers of resilience are often overlooked until disaster strikes. Whether you’re supporting a branch office or a full data center, this episode teaches you to think like a systems engineer—prioritizing uptime through proactive design.
