About 8 hours total across two days.

The problem? We were setting everything in our new self-hosted kubernetes cluster. Set up our CI/CD pipeline on it, but it wasn't able to build our stuff, specifically it failed to fetch stuff out to the internet.

The bug ended up been some missconfig MTU value somewhere between kubernetes, CI/CD, and the DinD used to build.

Two lines of config change later and everything is working fine
