        the node which shows up as down is indeed a 2.0.1 node

        Siri could you please take a look at the 10.3.121.83-source.zip ?

        In server log:
        2013-02-13T0:51:55.675 - Control connection to memcached on 'ns_1@10.3.121.83' disconnected

        Description: Network Disconnected, Name: Network 2, State: Disconnected

        So it appears that there is indeed a network disconnection. We need to investigate why. But as we've narrowed down the source of the problem to outside of the product, I would recommend moving this out of 2.0.1
