At StackVM we use an IRC bot to tell us when the servers are down. In our case the bot is just a DNode service so all the backend needs to do is connect to the IRC service, post its message, and disconnect.

It's a pretty great fit since we already use IRC a ton to coordinate development so we see the notifications right away.
