People use "root cause" to mean the true underlying driver. You can often restore service without knowing the true root cause. In this example, let's pretend true root cause is a memory leak that takes X days to crash Consul. It's possible they don't know that yet, and just shut down, cleaned up logs and temporary storage, added some capacity, and started back up in a region-by-region ramp up.
