That is a bit too minimalistic. How often do you ping? What do you do on no response at all or no DNS resolution? Do you send an email when the server is up again? Do you have different IP you ping from? Do you send a message when the server is up again? When you don't confirm emails, what is your strategy to prevent abuse? How can I stop/delete an existing monitor? Who are you? Why should I trust you?
