IIRC, their crawler pushes (or pushed) a lot of page into the Internet Archive Wayback Machine. What kind of effect will this shutdown have on it?
You can see this by looking at the "Items" graph on the Alexa Crawls collection [0]
(I am not associated with the Internet Archive - just a very happy user!)
Were they still providing value to the Wayback Machine at that point? Has their cessation had a significant impact on the Wayback Machine's crawling ability?
