In 2012, Numenta restricted access to a substantial part of its older HTM material: papers, installation notes, wiki pages and related media. For a while, replacing the old numenta.com host with mail.numenta.com/mediawiki made the legacy wiki reachable, so I updated references in my own posts.
That route later disappeared as well. I had crawled the legacy site for my research, but republishing the collected documents was not an acceptable solution: availability does not cancel copyright. The practical public alternative was the Internet Archive, which had captured much of the site’s HTML.
At the time I used this archived entry point:
Browse the July 2011 capture of numenta.com
The capture was incomplete.
My NuPIC installation note preserves one example of the runtime context those missing pages once supplied. Many PDFs, images and videos were absent even when the page referring to them survived. Still, the archived HTML helped recover titles, terminology, old installation paths and the context in which the early platform was documented.
This small episode changed how I treat technical references. A link is not an archive, and a local copy is not automatically publishable. Durable technical writing needs both provenance and a lawful preservation path. Where an original has vanished, an archived source should be labelled as such rather than silently presented as a current page.
