Hi Kristian, Once a node gets segmented, it can't be reconnected back to the cluster, because Ignite doesn't merge the data after split brain. This is done to guarantee data consistency.
If segmentation happens, you should stop segmented nodes and start them again. Note that in your scenario this will mean restart of the full cluster, because if connection is lost between data centers, all nodes will be segmented. Generally, in this case you may want to define which part of the cluster continues running and which one is restarted. This is not available in Ignite, however GridGain provides this feature as a part of their paid solution [1]. Also they have async data center replication that probably fits your use case better [2].
