How to Diagnose and Fix DNS Resolution Failures on Linux

Episode 34 of Linux Server Admin with Fexingo. Lucas and Luna walk through a real-world DNS failure that took down a staging environment for six hours. They explain how to use `dig`, `nslookup`, `systemd-resolved`, and `/etc/nsswitch.conf` to pinpoint the cause, and share a concrete fix using conditional forwarding in `systemd-resolved`. You'll also learn how to monitor DNS health with a simple custom script. Perfect for sysadmins who have ever stared at a blinking cursor wondering why `curl` hangs. Includes a quick note on how listener support keeps the show ad-free.
