I'm not technically versed enough in the running of the website, but apparently they're trying to find a relatively recent backup and restore the site from that, and using cached pages (either from our browser caches or google caches) is kind of a last resort if no backup can be found or restored. I assume the latter solution would entail us manually editing or creating over 8000 articles, which would suck. I'd suggest hanging on to whatever you have.

HOPEFULLY, we won't need them.
