The Memory Hole (web site) - Definition from the Hotspot Shield Glossary

This is a website launched in 2002 that was created as a storage repository for any information that was at risk of being deleted or lost from public knowledge.

The archives cover a broad range of subjects and areas including government files, memos and letters from corporations, patents, web pages, photographs and news articles. Much documentation on the internet or held in physical locations will not have a permanent “shelf-life” - materials will degrade and archives may be destroyed after a certain period of time. The memory Hole aims to combat this and ensure that as much useful data as possible is stored. The initial version of the website was ended in 2009; however a second version was created in June 2016.
