Episode 135: Diverse Paths and Internet Redundancy — Ensuring Availability

Redundancy isn’t just about hardware—it’s also about network paths. In this episode, we explore how having multiple physical and logical paths ensures internet and WAN availability. We discuss multihoming, diverse routing through different ISPs, and the role of BGP in managing multiple connections. You'll also learn how DNS failover and SD-WAN contribute to high-availability strategies.

We explain why path diversity matters not only for uptime but also for load balancing, latency management, and DDoS mitigation. Whether you're protecting a critical service or just ensuring smooth business operations, understanding how to design diverse connectivity options is key. This episode equips you to think beyond a single cable and toward a resilient, intelligent network.
