@TechConnectify Teaching good troubleshooting is a hard, and never ending task.

Some, nay most people will absolutely resist learning and adhering to a logical approach, and will regress to terrible methods without constant refreshes.

I have fiber service techs that STILL want to run out to the FDH(distribution point) and knock out a splitter's worth of subscribers for their first troubleshooting step.

But getting them to try replacing a local patch cable? Noooo, it can't be that! Better drive down the road and knock 7 other customers offline first!

Start with the easy shit, then start dividing and conquering. For such a simple concept, most people can't do it.
