RESOLUTION
Since the eighth of January 2008 autoinstall.plesk.com is working through CDN (Content delivery network) provider. It means that autoinstall.plesk.com is mirrored to several servers that are located in different regions over the world and autoinstall.plesk.com domain is resolved to different physical server in every location. This was done to speed up access to Parallels products for customers.Mirrors servers provide content only via HTTP, if you need to make local autoinstall mirror via rsync protocol, use the origin.autoinstall.plesk.com or rsync.autoinstall.plesk.com domains that are resolved to the original "autoinstall.plesk.com" (64.131.90.31).
