Checking if the server is down is better to be done by requesting for a service on some port and see the response status code.i'm sure i'd know whether or not my servers are responding to ICMP echo requests within my networks. BTW, i have noticed that some ISPs and many business networks discard outbound (at their border) ICMP echo requests. that might be a common cause of the issue. still, i see a majority of servers do respond. and this is why i plan to have various other options to "ping" another host, including DNS and other protocol based requests. and i may also want to only consider timely responses and a consistent sequence of responses as "up".
