OverSite monitors websites and shows an up/down timeline graph. Use OverSite to track when your Internet connection was up or down, by monitoring well-known sites. Monitor any number of web sites to see a timeline of when they are up or down. Within your router, monitor an individual computer's IP address to see when it is awake or asleep. OverSite uses Internet Control Message Protocol (ping), a lightweight mechanism to determine if a website is up or down.
