I never spent much time with networking so a lot of it was a bit of a mystery to me so I spent the COVID time building out really awesome but overly built network.
I learned a ton and can now actually understand what's going on under the hood!
Since then though I definitely have simplified it a lot because it was a lot to manage but it was an excellent learning experience.
This is my long winded way of saying, network engineers don't get enough praise - that shit is actually really damn difficult to get right at scale!
