Well, maybe your memory. From Tim Bray, an Amazon employee:
Obviously, indexing the whole Web is crushingly expensive, and getting more so every day. Things like 10+-year-old music reviews that are never updated, no longer accept comments, are lightly if at all linked-to outside their own site, and rarely if ever visited… well, let’s face it, Google’s not going to be selling many ads next to search results that turn them up. So from a business point of view, it’s hard to make a case for Google indexing everything, no matter how old and how obscure.
Competition Bing can find it! Duck-Duck-Go can too! Both of them can find Brent’s London Calling piece, too. More.
Reality check: Of curse, it may not be that simple, if Google needs us to not find something.
