"Internet Archive" is a project that keeps the website on the Internet, which has been released for free for more than 25 years, in chronological order.Internet Archive is operated by donations from various organizations and can access storage data from anywhere in the world.
When you access the Internet Archive top page, the input part "Waybackmachine" is displayed.If you enter the URL of the disappeared website here, you can see if the Internet Archive has already saved the data on the site.
In fact, Waybackmachine also has a keyword search function, so you can check if there is a saved site based on the keyword even if you do not know the URL you want to see.However, Internet Archive keyword search is low accuracy and cannot be expected to be a Google search.
