SiteUp monitors your web sites and warns you when any become unreachable (e.g. when a server crashes). Because it checks page content it can even detect when the server is OK, but a site or page is unavailable. There is no limit to the number of sites that can be monitored, including secure sites, and the checking frequency can be anywhere between once a minute and once a day. When a site goes down the system tray icon will change to an animated alarm and optionally you are displayed a warning message. When a site becomes available again you can view a log to determine how long the site has been down. SiteUp is licensed as freeware, full size of the download is 0.90 MB. You can download a free version of SiteUp by following download link at Free Downloads section of this page.
