While I'm glad I'm not the only one experiencing the issue I'm sorry you are too. I parsed out every file in the support bundle and no files reference the hostname or IP of the DC that was offline. The connector logs do reference the DCs that are in the domain file under 'java.naming.provider.url' and those are the correct two based on AD Sites + Services. Not sure if I need to enable more verbosity somehow or if the logs fail to show which DC is really being contacted.
