Jason Scott from the Internet Archive commented on Lars' blog post, offering to maintain the archive up at the same domain gmane.org https://lars.ingebrigtsen.no/2016/07/28/the-end-of-gmane/com...

This is undoubtedly good news, and prove once more what fundamental role the Archive has on the internet. I personally hope they will not only keep the content up, but will continue Lars' work on actively running Gmane.
