Which mirror do you use?

I got some issues with all my mirrors: the size of the last pacman package is very (too) small (60 vs 944412 for previous version). e.g. https://archlinux.uk.mirror.allworldit.com/archlinux/core/os...

Most of the US ones now are synced. I haven't tried out other countries. Initially, there were ~130 that I tried and got a 404 on all of them for the latest pacman. When I tried again a about half an hour ago, only ~50 of the US mirrors returned a 404

I would try and generate a new mirrorlist for your locale: https://archlinux.org/mirrorlist/
