Open missing sites and pages not found (404) from the cached copy

Browsing far and wide through the vast sea of ​​the internet, we get hurt when we discover that some of the most interesting and useful sites have disappeared and no longer exist. Unfortunately internet sites are born and die like flies: new ones are discovered every day and many others disappear. In some cases an internet address refers to a completely different website from what was expected, in other cases we discover pages such as " domain for sale " or simply warnings with the words " error 404, page not found " or " unable to connect "
Error 404 indicates that a site no longer exists or that it has been taken offline without leaving any communication. Also, unfortunately not so rarely, some blog articles or online newspapers are obscured and censored if they contain information that is inconvenient to someone.
Fortunately, every time you discover a web page not found with 404, you can always retrieve it using the cached copies that some other sites automatically and periodically save.
First of all, it would be appropriate to check if a site is not accessible for everyone or if there are connection problems for your computer.
If the site is unreachable, then its cached copy can be opened. The cached copy is an exact copy of a site that is downloaded, saved and reposted in another domain.
The best site to open a site that no longer exists and is now gone is definitely Google which, for each page indexed in its search engine, maintains a freely visible and legible cache copy. When you search on Google, leaving the mouse over the title of a web page, you can click the arrow on the right to see the instant preview and then view the cached copy of that site. This page resides on Google servers therefore, even if a site has disappeared or cannot be reached, it will be visible in its latest version.
Google is not the only site that stores a site's cache page, there is also the Microsoft Bing search engine that allows you to open the page in the cache, indicating the date and time when it was downloaded or saved. .
Not all pages on the internet have a cached copy such as, for example, pages specially blocked by its creator and very recent ones. Even the sites that have disappeared or been deactivated for some time no longer have a cached copy because they disappeared from the search engines or, if the site has changed, the copy of what was there before is no longer available.
For very old sites, the place to look is the Internet Archive Wayback Machine which also allows you to explore the history of the internet and what sites were like many years ago. The Wayback Machine is a digital time capsule created by a non-profit organization that uses the contents extracted from the Alexa site, archiving copies of the sites over time. For some sites copies are saved more frequently while for others there are only snapshots captured once or twice in more years. The storage frequency is highly variable and can be at intervals of several weeks or years.
