Answer 1

Apple provides reachability classes you can use the class and

You can download reachability.h and Reachability.m

And use this as

Reachability* reachability = [[Reachability reachabilityWithHostName: @"www.apple.com"] retain];
NetworkStatus netStatus = [reachability currentReachabilityStatus];

netStatus gives the reachabilty of the server.

If you want to ping the server, try this:
