The crawl archive for June 2017 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2017-26/. It contains 3.16 billion+ web pages and over 260 TiB of uncompressed content.

Data Type File List #Files Total Size
Compressed (TiB)
Segments segment.paths.gz 100
WARC warc.paths.gz 71839 63.33
WAT wat.paths.gz 71840 21.06
WET wet.paths.gz 71839 9.44
Robots.txt files robotstxt.paths.gz 71840 0.13
Non-200 responses non200responses.paths.gz 71840 1.77
URL index files cc-index.paths.gz 302 0.24
Columnar URL index files cc-index-table.paths.gz 900 0.27

To improve coverage and freshness we used the top 40 million ranked hosts from the Feb/Mar/Apr 2017 webgraph data set and added almost 800 million new URLs (not contained in any crawl archive before), of which:

  • 500 million URLs were found by a side crawl within a maximum of 3 links (“hops”) away from the home pages of the top 40 million hosts;
  • 300 million URLs are a random sample extracted from sitemaps (if provided by any of these 40 million hosts).

About 33% of the crawl archive's 3.16 billion URLs overlap with the preceding May 2017 crawl.

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-2017-26/. 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 info@commoncrawl.org for sponsorship information.
