The site is a very simple and easy to understand.  In the first box, just put the domain URL that you wish to monitor (specify whether it is a HTTP or HTTPS) then enter the email address at which you would like to be notified.



As you can see though, Was It Up? also has another feature and that allows you to monitor the front page for a keyword to appear (or not appear).   In my example above, I am asking the app to monitor and alert me if the front page gets hacked with sexually explicit keywords.   But you can use this feature in other ways such as being alerted when a particular post, with particular keywords, reaches the front page of your domain.   So this app is a particularly useful page tracking tool.

This already useful tool would get even better though if alerts were sent to a Twitter account or a mobile phone.

Feature:

• Monitors your website and alerts you if it goes down.
• Also monitors you home page for hacks.
• Sends alerts via email.

It collects data on websites from users in different countries.  Here is how it works: First you visit the homepage and enter the website URL that you can’t access. Then hit “Enter” to view current reports.

If the site was reported as accessible, then it’s likely that the site is down just for you (eg. problem with your internet connection, corporate firewall). If it was reported as inaccessible by users in your country or other locations worldwide, then its likely to be a common problem.



To check whether the sites are down/inaccessible while you browse, install a browser add-on for Firefox. If it shows green then the site its fine. On the other hand, if the color is yellow, it means a site was recently inaccessible in some location(s) worldwide.





Participate and report on inaccessible websites by clicking “Report this site…” in the add-on. It makes the tool more useful for everyone using it.

Features:

• Check whether a particular site is inaccessible for everyone or just you.
• Data collected from Internet users around the world.
• Install Firefox browser add-on to check the real time accessibility of sites you browse and report on inaccessible sites.
• View inaccessibility reports over different periods of time (days, week, whole year).
• Project of the Berkman Center for Internet & Society at Harvard University.
