Is IP Failover is working between 2 root server on different datacenter ?

    Hi,

    I have 2 netcup root server

    - 1 root server in Germany DC1

    - 1 root server in USA DC2

    Is it possible to have an IP failover between those 2 DC so if DC1 is down I can switch to DC2 ?

    or IP Failover is only working between 2 server inside the same DC ?

    thanks
