If you're a web developer like me, you probably have a cadre of sites that you manage. When a client calls *you* to inform you that her site is down...that's bad. If you're using a shared hosting provider, downtime is inevitable, but your life is going to be much better if you know a site is down before she does.

Enter Pingaling. Pingaling is a very simple Windows command line tool that I created for checking to see if sites are up or down. If a site is down, Pingaling sends you a notification email and you can take corrective action if necessary. Set Pingaling to run as a frequent Windows System Task and you can fire and forget.

You can learn more about Pingaling on my GitHub project page.
