Hi,

When you define a replication environment, you create replication groups and add master sites to these groups.

The propagation mode is defined for each group, not for all the repliaction environement. If you define a repliaction group with propagation mode set to synchrnous, then you are right, if a master is not available, all the transactions will be rollbacked.

This is the expected behavior for this propagation mode.
