While considering how much I should trust https://archive.org I started looking for its source code.
However, despite expecting it to be open source, due to the not-for-profit open culture nature of the organization, I couldn't easily find the source location.
So, is the source for the website open source, and if yes, where is the source?
The best I could find was the source code for their crawler: http://crawler.archive.org/index.html but I'm guessing this is only one part of the project.
They also have a GitHub organization with several projects: https://github.com/internetarchive but I'm not sure if the most important ones are there. There is a repo https://github.com/internetarchive/wayback though, which is entitled "IA's public Wayback Machine (moved from SourceForge)" and has a two line README.
There appear to be some bug trackers at: https://webarchive.jira.com/secure/Dashboard.jspa although they seem to have little activity as of 2020.
