Website Monitoring is not enough
If you're currently using a Web Site/Application monitoring system to help ensure that your Facebook application is always up and healthy, that's terrific - we like to work with people who use good practices. We think you'll also like FriendRunner Alert since it provides protection that you aren't already getting.
Web monitoring systems answer the question:
Is my application healthy and accessible from the Internet right now?
FriendRunner Alert, on the other hand, answers the question:
Is Facebook going to release something that will break my application?
Yes, without FriendRunner Alert your Web site monitoring system will let you know that your application was broken by Facebook. The bad news is you'll get that warning AFTER all of your customers have already experienced it. FriendRunner Alert warns you BEFORE so that you have a chance to proactively fix it or report the problem to Facebook.
