Is your bookmark leading to an empty webpage? Did that link you found on a forum post dated 5 years ago no longer work? Perhaps you need some information from a site and it’s currently down for maintenance?

The Wayback Machine is useful for seeing historical snapshots of web pages as well, and seeing how web pages change through time.
