SoftLayer customer servers that are purchased with the Microsoft Windows operating system are configured by default to retrieve updates from SoftLayer's local Windows Server Update Services (WSUS) server. Periodically, these servers synchronize and check for new updates from their local WSUS server. SoftLayer_Container_Utility_Microsoft_Windows_UpdateServices_Status models the results of a server's last synchronization attempt as queried from SoftLayer's WSUS servers.
