The appliance does fail-back and takeover and there is an important distinction between them since the former requires resources be exported before they are imported by the other head, whereas takeover just imports them.

In the case of a slow fail-back, its worth figuring out if the relinquishing head is slow to export or whether the claiming head is slow to import the resources.
