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.

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 to each line, you end up with the S3 and HTTP paths respectively.
