Website uptime alarm system - Free
Posted by David on April 20th, 2006 filed in FeaturesWhen the site is running, you received the guaranty, that the uptime of your website is 99.9%. It is equal to 365day times 24 hours times 0.001. The result is 8.76 hours. How do you know the real uptime of your site.
You can depend on the log file of your site, or uptime report from your Host company. It is not enough. You need more third-party tools to monitor your website.
There are some websites provide these services. Some of them provides the very basic service freely.
InternetSeer Web Site Monitoring Service
It provide free service for monitoring one URL only. The frequency for checking your site is 60 minutes. The contact can be over more than one. The contact way is by eamil only.
To get more monitoring items, you have to join its InternetSeer Priority Club
It cost you $29.95 a year. It is worth to get it.

My personal suggestion is try their free service first. If you satisfaction ratio is high than the 99.9%, like above guaranty uptime percentage, you can join the Priority Club.
One more choice, 
The Killer Website Monitor is FREE and easy to set up
The Killer Website Monitor is a software system designed from the ground up to monitor websites 24/7. You can think of it as a security system for your website.
If the Killer Website Monitor can’t reach your website, it will immediately send you an email alerting you that your website is unreachable - protecting your investment and allowing you to take action to get it back up quickly.
This one only provide one site and contact one person by eamil.
Compare with these two services, the Killer Website Monitor is only suitable for the small site or personal site. If you have many sites and if somehow the site is down, you need to inform two or three contact person, you need InternetSeer.
