■ Internet Archive - Lost contents
By Sunblade

When the Internet Archive (archive.org) was still new over 20 years ago, it is easy to suppose it had a limited capacity for that period.

For this reason, some old content are just partially archived or not archived at all.

Typically:

* Sites, articles, contents that didn't have a good quantity of pageviews
* Softwares, games, etc that didn't have a good quantity of downloads
