The site is up, but it's not functional. Apparently they relied on a simple, static interface to search and Google has removed it, so they aren't able to perform searches anymore. (Which they will tell you if you do try to do a search.)
More information here: http://www.scroogle.org/cgi-bin/nbbw.cgi „We regret to announce that our Google scraper may have to be permanently retired, thanks to a change at Google. It depends on whether Google is willing to restore the simple interface that we've been scraping since Scroogle started five years ago. Actually, we've been using that interface for scraping since Google-Watch.org began in 2002.“
