I am trying to setup a remote cyrus-replica to a different geographical

In case the main server goes down the users will get switched to the
remote server by making a DNS change.
The only issue is DNS replication would take a long time so the switch
is not instantaneous.
How would one make the switch instantaneous ? Moving the IP is not
possible because the Remote server is on a different network



You can set TTL of RR to very small value (say 60 seconds). In this case, DNS change will be propagated fast.
