If there is a page, that isn't archived in the Waybackmachine how can I add this site to the archive? Or is there another service like that where you can add custom sites to be archived "forever"?
I would like to be able to proove that the site existed like I took a screenshot today.
Does this also work for https-sites?
I found this in the FAQ: My site’s not archived! How can I add it?
but it doesen't work for that page: https://github.com/ZachWick/TableCSVExport
Some other pages have stated, that
Page cannot be crawled or displayed due to robots.txt.
like http://web.archive.org/web/*/https://github.com/gilbitron/WordPress-Settings-Framework
But http://web.archive.org/liveweb/https://github.com/ZachWick/TableCSVExport just shows the live page
