February 2017 Crawl Archive Now Available
The crawl archive for February 2017 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2017-09/. It contains 3.08 billion+ web pages and over 250 TiB of uncompressed content.
To extend the coverage of the crawl we
- continued to use sitemaps to find fresh URLs for known hosts;
- added 250 million URLs within a maximum of 2 links (“hops”) away from the home pages of the top 5 million hosts. We also ranked these hosts by Harmonic Centrality calculated on Common Search’s host-level webgraph using HyperBall;
- again, used verified, DNS-resolvable domain names of European country-code TLDs (.eu, .fr, .be, .de, .ch, .nl, .pl, .ru, .dk), thanks to the continued donation of seed data from webxtrakt;
- included 3 million URLs from dmoz.org (formerly, the Open Directory Project).
The link extraction for WAT generation has been improved to include links to embedded content. See issues 7 and 9 on GitHub for further information.
To assist with exploring and using the dataset, we provide gzipped files which list all segments, WARC, WAT and WET files. By simply adding either s3://commoncrawl/ or https://data.commoncrawl.org/ to each line, you end up with the S3 and HTTP paths respectively.

The Common Crawl URL Index for this crawl is available at: https://index.commoncrawl.org/CC-MAIN-2017-09/. 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.
