We have two new hosted machines, each of which has suddenly and
unexpectedly lost connectivity. In each case connecting a console and
typing "ifup eth0" restored connectivity. Nothing at all appeared in
/var/log/messages between the last good log, and the insertion of the
USB keyboard for recovery.
We're pretty perplexed. Any hints for us? Is there anywhere else to
look for logs or records of how the interface might have come down.
