Hmm I was going to run my own tests but it seems the servers are actually down currently:
(@v1.4) pkg> up
Updating registry at `C:\Users\Jeremy\.julia\registries\General`
┌ Warning: could not download https://pkg.julialang.org/registries
└ @ Pkg.Types D:\buildbot\worker\package_win64\build\usr\share\julia\stdlib\v1.4\Pkg\src\Types.jl:889
https://us-east.pkg.julialang.org/ is down but https://us-west.pkg.julialang.org/ is up.
