Code for seeing if a website is down?

Question

I'm trying to replicate sites like http://www.downforeveryoneorjustme.com or http://doj.me. Any ideas about the coding?

Edit: could I also have some source code examples?

use cURL and see if you get any sort of response at all. – Cyclone Dec 19 '11 at 23:29 — Cyclone, Dec 19 '11 at 23:29

You could use get_headers() and check to see if returned anything but 200 OK.

You could also try a HEAD request, but there is a small chance a server may respond differently than a GET.

I'm not sure that checking for HTTP 200 is part of the test: it may return a 404, but that still indicates the web server is alive.. What about just checking port 80? – redShadow Dec 19 '11 at 23:39

You could try curl to see what response headers you get back from the specified url. Then go from there I guess.
