The idea is to use the free CoralCDN (http://www.coralcdn.org/). HN could solve site-killing by prefetching every link with CoralCDN, so that the CDN would cache a version of the page. Then, if HN detects that a site (e.g. http://allrgb.com/) is down, it would link to the Coral version (e.g. http://allrgb.com.nyud.net/) until it’s up again. Or alternatively, instead of detecting when sites are down, it could show a control to replace any given link with the CoralCDN version and ask the user to toggle it if the link doesn’t work at first.
