The Hidden Cost of Internet Redundancy

Most people assume that having two internet connections means double the speed. In reality, it usually just doubles the complexity and cost without fixing the real bottleneck: asymmetric routing and stateful firewalls. This episode explores how network engineers manage failover in high-stakes environments like data centers, using specific protocols like VRRP and BFD to keep traffic flowing when a primary link goes down. We look at why simple load balancing often fails under pressure and what actually happens to your TCP handshake when a path changes mid-flight. If you run a business or just care about uptime, understanding the difference between active-active and active-passive configurations is crucial for building resilient infrastructure that doesn't collapse on itself.
