XDCR is resilient to intermittent network failures.

In the event that the destination cluster is unavailable due to a network interruption, XDCR pauses replication and then retries the connection to the cluster every 30 seconds. Once XDCR can successfully reconnect with a destination cluster, it resumes replication. In the event of a more prolonged network failure where the destination cluster is unavailable for more than 30 seconds, a source cluster continues polling the destination cluster which may result in numerous errors over time.
