No, if the server stays down, Ping will alarm as soon as scheduled downtime 
expires (+ 0 to ping interval additional time). If the server comes back up 
enough to respond to ICMP echo requests, but does not complete booting, all 
the service checks will alarm due to freshness checks (assuming you have 
something being monitored on that host).
