Always test.
But if you only had one AZ then all nodes will be in one Rack, so the NTS will
not behave differently.

multi racks I will make sure to use them properl

If the nodes can directly communicate with each other, say through a VPN, you
may not need to change it.
If they are behind a NAT you will need to use it.
When you change the snitch test f
