A number of online services can report your uptime and let you know when your website is down. Most use something called “pinging” the website. When you ping a website, it gives a response and lets your know the server/website is working properly. We recommend using Pingdom to test your website. Pingdom will send a ping to your website at different intervals automatically, and if the website does not respond, it will send you an email. When the website is back up, it will send you another email. Pingdom will also keep track and give you a report of how much your website is up (uptime). A basic account with Pingdom is totally free. Their website is http://pingdom.com.
