This is more than I need =), but will keep it in mind when I have a dedicated 
server host plan. Right now I just wanted a way to monitor if my website is up.

I guess the server could still be up so a simple ping test would not tell me if 
the webserver was down. I could do both a ping and http request for to test my 
site is up and running.

I was looking for another site that would monitor website and send me an email 
or sms text when it become offline.
