Where oh where has my friend's server gone? [closed]

Is there a tool that will monitor Minecraft servers and notify you when they come online?

How hard would it be to make such a tool? How would you check without using the Minecraft client?

I think this is what your looking for : Minecraft Server Status Checker

If you wish to write such an app, the base code that the accepted answer uses is here.

By default, the Minecraft server communicates via port 25565 - so check that port on your friend's server for activity perhaps?
