March 2017 Crawl Archive Now Available
The crawl archive for March 2017 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2017-13/. It contains 3.07 billion+ web pages and over 250 TiB of uncompressed content.
To improve coverage and freshness we ranked all hosts found in the February 2017 crawl by Harmonic Centrality, and
- added 600 million URLs within a maximum of 2 links (“hops”) away from the home pages of the top 8 million hosts;
- used sitemaps (if provided by any of these 8 million hosts) to take a random sample and add further 100 million URLs.
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-2017-13/.
