I don't know if you can get spread to tell you, but in this scenario I've used a
3rd server that periodically sends a "heartbeat" message to the same spread
group and a listener which then updates the timestamp on a file when the
heartbeat is received. And then we use Nagios to monitor the age of that file.
Not perfect, but if there are network problems we know about them soon and only
loose an handful of messages.
