IsItUp - When you need to know the status of your network. IsItUp monitors multiple network, email, website devices around the clock and notifies you, via email or pager, of the status of that device - when it goes dow n, and when it comes back up! IsItUp maintains complete statistics for each device it monitors - up time, maximum response time, minimum response time, standard deviation and a host of other measurements. What's more, it tracks the last successful and last failed Traceroute to a destination so it can determine where the break-down occurred.
