Julia registry not getting updated

I updated my package https://github.com/ufechner7/KiteModels.jl to version 0.3.3 eight hours ago, but if I do:

mkdir tmp
cd tmp
julia --project="."
using Pkg
Pkg.add("KiteModels")

I still get version 0.3.2.

Is the package server infrastructure for Europe (NL) broken?

I created a bug report: PkgServer synchronization · Issue #59568 · JuliaRegistries/General · GitHub
