关于这个附加组件
This CheckSite.us Add-on allows you to quickly use CheckSite.us to check any website that you cannot access to see if it really is down or not. If the website happens to be down, you can then enter your e-mail address and CheckSite.us would automatically continue checking the website for you and e-mail you as soon as it can access the website.
