I remember reading somewhere that once You include some url in robots.txt archive.org even though can have it archived it will stop showing it to the public.

https://blog.archive.org/2017/04/17/robots-txt-meant-for-sea...

https://github.com/robots.txt

They have some interesting nuggets in their robots though like `/ExplodingStuff/` and `/account-login` both of which seem to be some accounts.

Or probably more possible - they just got in contact with the archive.org people.

Apart from the code linked above, I don’t think you’re missing any significant information that was on that archived page whose URL is now excluded. The screenshot at the top of this article matches what I remember of that page: https://arstechnica.com/information-technology/2020/11/githu....

To describe the screenshot in words, for the sake of those who prefer text to images for whatever reason: the commit was an orphan with no parent; it had no commit history. The message was as SethTro quoted it: “felt cute, might put gh source code on dmca repo now idk”. GitHub’s interface suggested the committer was https://github.com/nat, but there was no “Verified” label. The interface described the commit as having been created “1 hour ago” at 2020-11-04 05:00:26, the time of crawling.
