The Wayback Machine is a digital archive of the World Wide Web created and maintained by the Internet Archive. It allows users to access and view websites as they appeared in the past, with over 500 billion archived web pages.
To use the Wayback Machine, simply enter the URL of the website you want to view into the search bar on the homepage. You can also browse by date or use the "Save Page Now" feature to save a current version of a website for future access.
The Wayback Machine does not archive all websites, as it relies on web crawlers to collect data. Some websites may also have restrictions in place that prevent them from being archived. However, the Wayback Machine does have a vast collection of archived websites, including popular ones like CNN and Wikipedia.
The Wayback Machine has archived websites dating back to 1996. However, not all websites have been archived consistently, and some may have gaps in their history.
The Wayback Machine strives to be as accurate as possible in preserving websites as they appeared in the past. However, there may be occasional errors or missing content due to technical issues or website changes that were not captured by the web crawlers.
