The crawl archive for December 2016 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2016-50/. It contains more than 2.85 billion web pages.

Similar to the preceding September and October crawls, we used sitemaps to find new URLs for already known hosts shortly before the crawl was launched. In addition to the top-million domains from Alexa, sitemaps were mined for a list of multi-lingual sites. Thanks to the Statistical Machine Translation Group at the University of Edinburgh, which created this resource and made it available. We hope to have greater coverage of multi-lingual content in this and future crawls.

We are also grateful to webxtrakt for the continued donation of verified, DNS-resolvable domain names of European country-code TLDs (.eu, .fr, .be, .de, .ch, .nl, .pl, .ru, .dk).

To assist with exploring and using the dataset, we provide gzipped files that list:

By simply adding either s3://commoncrawl/ or https://commoncrawl.s3.amazonaws.com/ to each line, you end up with the S3 and HTTP paths respectively.

The Common Crawl URL Index for this crawl is available at: http://index.commoncrawl.org/CC-MAIN-2016-50/. Note that the index now contains robots.txt responses and URLs that have not been successfully fetched (i.e. 404’s and pages with HTTP status codes other than 200). For more information on working with the URL index, please refer to the previous blog post or the Index Server API. There is also a command-line tool client for common use cases of the URL index.

Please donate to Common Crawl if you appreciate our free datasets! We’re also seeking corporate sponsors to partner with Common Crawl for our non-profit work in open data. Please contact [email protected] for sponsorship information and packages.
