    Hi all,

    I would like to setup two servers in two different DC's, that are hosting exactly te same applications (ISPconfig3) / mail / websites.
    This so when one of the servers goes down, the other server will automatically takeover.

    Anyone here who might know how to do this?

    The problem is that you need a failover IP, but for a failover IP, both servers must be in the same subnet...

    Okay.. I guess different DC's is a no go.. So how can I do this if the two servers are in the same DC and same subnet?

    For the High-Availability setup, you need the virtual IP and heartbeat or ldirectord (there are a few tutorials in the HA category that should give you the idea). To sync data on both servers, I'd probably use a combination of rsync (for files and directories) and MySQL replication (for the database).
