Progress Linux is distributed all around the world using mirrors in order to provide users with better access to the archive and to reduce the load on the servers. All mirrors are automatically updated whenever there are updates to the archive-master.
Progress Linux by default uses GeoIP to select the geographically closest server. All primary and secondary mirrors are participating in this mechanism.
|—||cdn.archive.progress-linux.org||packages images||HTTP HTTPS|
A primary mirror contains both the package archive and the images archive, supports all protocols (http, https, ftp, and rsync), and is operated by the Progress Linux association.
|Europe (Zurich, Switzerland)1||archive.progress-linux.org||packages images||HTTP HTTPS FTP RSYNC|
|Asia (Singapore)||as.archive.progress-linux.org||packages images||HTTP HTTPS FTP RSYNC|
|Europe (London, United Kingdom)||eu.archive.progress-linux.org||packages images||HTTP HTTPS FTP RSYNC|
|USA (Seattle, WA)||us.archive.progress-linux.org||packages images||HTTP HTTPS FTP RSYNC|
A secondary mirror contains at least the package archive, supports most of the protocols (at least http; and any or none of https, ftp, and rsync), and is operated by volunteers.

1 The main server is used as a fallback whenever there is no better local mirror available. Note that the main server does not get updates any faster from the archive-master as any other mirror.
