s390x has network issues
We are seeing network issues on our s390x boxes.
The most notable is via CI where apk takes ages to install packages. I also noticed issues with wget on the host itself, it was very slow where curl would be really fast. I upgraded the CI box from 3.10 to 3.11 (including new 5.x kernel) and this seemed to kind of fixed the issue with wget. But the problem with apk in CI/docker stays the same.
