I do know that Microsoft changed update servers on July 8th to
$server = Get-WsusServer
$config = $server.GetConfiguration()
# Check current settings before you change them 
$config.MUUrl
$config.RedirectorChangeNumber

Open in new window

returns
PS C:\Windows\system32> $server = Get-WsusServer
$config = $server.GetConfiguration()
# Check current settings before you change them 
$config.MUUrl
$config.RedirectorChangeNumber
https://sws.update.microsoft.com
