And you are absolutely correct. If you are in MAX Availability and the link is lost from the Primary to the standby and then you have a catastrophic loss of the primary (as in the entire system is totally lost to a fire for example), you will lose some data. And you wouldn't really know how much.
...

If the system is absolutely mission critical you should have more then one standby (three is a good number)
...

Good to have a confirmation ("Great Minds Think Alike" ;-))

As far as I understand we need

1. three standby databases
2. running in *data protection mode*
3. connected with reliable (separated?) networks

to have high availability *with data protection*, don't we?
