Plesk High Availability Cluster

Have you ever had an issue with a Plesk server when it stops providing service for the Internet due to hardware, network or software problems? What if I told you that it is now possible to switch a load from the broken server to another one in just a few minutes or even less? Meaning you will not need to rush to fix an issue on the broken server or even start receiving lots of calls and messages from customers about their websites being unavailable because, after switching, the websites will be available!
