Common Crawl Foundation provides another opportunity for Google challengers:
Google’s stranglehold on search information is seen by many as being contrary to the Web’s ethos of freely available information and openness. Now we have a way to access an index created to make the web more open. The new index has been announced by the Common Crawl Foundation.
The Foundation says: "Common Crawl is a Web Scale crawl, and as such, each version of our crawl contains billions of documents from the various sites that we are successfully able to crawl. This dataset can be tens of terabytes in size, making transfer of the crawl to interested third parties costly and impractical. In addition to this, performing data processing operations on a dataset this large requires parallel processing techniques, and a potentially large computer cluster. Luckily for us, Amazon's EC2/S3 cloud computing infrastructure provides us with both a theoretically unlimited storage capacity coupled with localized access to an elastic compute cloud."
