With Pager you can set how often to check your websites. Pager checks to make sure that these sites can be loaded, and reports to you when they can't. You can even use Pager to save a copy of the website and check to see if it's changed. Let Pager notify you when your favorite news site or forum updates.
Not at your desk all day? Pager makes sending text messages to your cell phone to report on downtime a breeze.
