Arch Linux: pacman -Syyuu does not change mirrors

I am currently installing Arch Linux on a new computer using a Live USB. While installing basic packages, one package failed to download.

> pacman -Syu --needed sudo gnome gnome-extra amd-ucode

wireplumber-0.5.10-1-x86_64.pkg.tar.zst failed to download
error: failed retrieving file 'wireplumber-0.5.10-1-x86_64.pkg.tar.zst' from cdnmirror.com : The requested URL returned error: 404

error: failed retrieving file 'wireplumber-0.5.10-1-x86_64.pkg.tar.zst' from mirror.theash.xyz : The requested URL returned error: 404

[The package was updated yesterday](https://archlinux.org/packages/extra/x86_64/wireplumber/) so I assumed the mirrors do not have the latest version yet. I tried refreshing the mirrors.

> pacman -Syyuu --needed sudo gnome gnome-extra amd-ucode

Pacman did refresh the package list but still tried to use the same 20 mirrors, none of which had the latest version of the package. What command forces pacman to try other mirrors, or even better, actively find mirrors that are up to date? [Edit] Tried out

as suggested in the comments.
