This server was rebooted this morning.

The machine was entirely unreachable on the network until 09:51 when the
ifdown/ifup was run. After the ifup and a delay of a few seconds, the
NIC seemed to come up again.
On a server rebooted yesterday, we saw exactly the same thing. The
network card was replugged a few times as part of the debugging (hence
the link up/down messages). Again, after the ifup/ifdown the card came
back up.
