There is a very useful package Unitful that I use infrequently.
https://github.com/PainterQubits/Unitful.jl
Thing is that the README links to https://ajkeller34.github.io/Unitful.jl/stable which seemingly disappeared but his Github profile still exists
I’m a bit afraid for the package as a whole…
The links should be updated to Home · Unitful.jl. Golden chance for a simple Pull Request if you are up for it!
As a new father, I really wanted to know how package docs could be diapered… I should be an expert by now 
It would have been good to replace the old github pages with a redirect, most of the top google links are broken too.
That is actually the problem here. I found the package over google and always considered ajkeller’s version to be the official one
It was until about a couple of days ago. The repository has been simply moved.
