Issue Adding new region to master

Hi All,

When we are adding new regions to the master db it is causing the existing regions to refresh and sometimes disconnect from the replication. This causes us to have to reconnect the ones that have disconnected which causes another refresh of all the connections and then can cause the same issue to a different region. This can go on for a while until we eventually get all the regions replicating. Is there a way to add the region without causing the existing ones from having to refresh as well? Is this normal behavior when adding regions?

Thanks
