Load balancing is available to customers with two or more VPS.
The software used for load balancing is Linux Virtual Server which supports a number of protocols include HTTP, HTTPS, and FTP. We use this software on a number of our own sites including AusGamers.com and this site (Mammoth Networks).
At this point in time, load balancing is enabled manually on user request - if you would like it set up for your VPSs, please contact our support staff to arrange a set up.
As such, there is no customer interaction with the load balancing configuration - our default configuration is to weight the servers evenly using round robin as the algorithm - if this is not suitable, alternate weightings and/or algorithms can be provided such as 'least connections'.
To turn a server off, you simply perform a graceful shutdown of the web server software so that it services existing requests while refusing additional requests - the load balancer will notice it refusing connections and fail it out of the pool.
