I know it is about a month old, but we were having a similar problem in the past. Our AD connector would stop syncing and the only way to fix it was to restart the OpenDNS Connector service on the server. This would happen about once a week. What ended up being the solution for us was to actually deploy a second AD Connector on a separate server, we haven't had any problems since then.

Also, for re-syncing DC's to the Umbrella tenant:

What I have done when one of our DC's has had an error is just re-run the script provided in our tenant. This has never caused any problems on any of our DC's.

Hope this info helps.
