As of recent changes to cPanel, Servers Australia now hosts it's own fast-update service.
If you would like to utilise this, you are able to add the following to /etc/cpsources.conf, in order to configure your cPanel to run updates against our FastUpdate Server.
It can be done from the Command line, using the below command.
echo "HTTPUPDATE=220.127.116.11" >> /etc/cpsources.conf
Once this is in place, your services should by default download updates for cPanel processes using our cPanel FastUpdate Server which is served on a gigabit backbone for Servers Australia Customers.
