Are you saying you only have 1 seed node in the seeds list of each node? We recommend 2 nodes per DC as seeds -- if one node is down, there's still another node in the local DC to contact. In the worst case scenario where 2 nodes in the local DC are down, then nodes can contact seeds in other DCs. For the second item, could I make a small request? Since it's unrelated to this thread, would you mind starting up a new email thread? It just makes it easier for other users to follow the threads in the future if they're searching for answers to similar questions. Cheers! >
