The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Ping would be unreliable. It doesn't guarantee that the service is up.
If any checking is to be done it needs to be at the layer that the
service runs on (eg. TCP / HTTP / etc). even then your application
should be aware when a TCP connection breaks and handle the failed
transaction then.

In CL you could do
PING RMTSYS('NRA.ORG') MSGMODE(*QUIET *ESCAPE)
MONMSG MSGID(TCP3210 TCP3202 TCP3213) EXEC(GOTO CMDLBL(ALERT))
If that fails, grab your guns and head for the woods. :-)
Caution: Some sites block pings.
I know jack about sockets programming but couldn't you open a socket to
the target and see if they are up?
