Just rolled out a new 'Stats Overview' area at Downtime Monkey where you can view a summary of the stats for all your monitors at a glance.
There have been several requests for this feature from customers who want to view the most important stats for all their websites in one place.
The main advantage is that you can see the pertinent uptime and response time figures in a split second, immediately becoming aware of any problems without having to click between pages.
