Void Linux maintains mirrors in several geographic regions for users. A fresh install will default to repo-default.voidlinux.org, which may map to any Tier 1 mirror, but you may have a better experience by selecting a different mirror.
See xmirror.voidlinux.org for more information and a list of available mirrors.
Void Linux is also mirrored on the Tor network. See Using Tor Mirrors for more information.
