When Your DNS Dies: Home Network Failure Cascade

A single server failure triggers a catastrophic cascade: ZFS pool corruption takes out DNS, the Unifi controller, and every service that depends on them. Your WiFi stays up but you can't adopt new devices, push config changes, or even search for error messages. This episode walks through the specific failure mechanics—flaky SATA cables, TLS verification breakdowns, and the chicken-and-egg loop of needing DNS to restore DNS—then examines the real tradeoffs between a single point of failure and a sprawling rack of Raspberry Pis.
