#!/bin/sh
err=2 # Ping return value on error
ping -c1 host1 > /dev/null 2>&1
host1=$?
ping -c1 host2 > /dev/null 2>&1
host2=$?
ping -c3 host3 > /dev/null 2>&1
host3=$?
if [ $host1 -gt $err -a $host2 -gt $err -a $host3 -gt $err ]; then
   echo "Network is down..."
fi


Could surely be refined, but it works ;-)
