There is no doubt that uptime is one of the most important factors to running or owning a web site.  So if a web site goes down, common sense would tell you that you want to know about it, right?  A new service called Ding It’s Up! will help you keep track on your domain or any other domain you give it.

Here is how the service is described via the official web site:

Ding It’s Up is a free service that alerts you via text (SMS), twitter or email when a website goes down or when it comes back up. We will never send you a text/email unless it is to inform you about a website you requested information for – you can unsubscribe at any time.

Now I would not rely on just using this tool to keep tabs on your web site, but it does make a nice accessory to other tools you could use.
