The crawl archive for July 2018 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-30/. It contains 3.25 billion web pages and 255 TiB of uncompressed content, crawled between July 15th and 23th.

The July crawl contains 625 million new URLs, not contained in any crawl archive before. New URLs are “mined” by

  • extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the Feb/Mar/Apr 2018 webgraph data set
  • a breadth-first side crawl within a maximum of 6 links (“hops”) away from the home pages of the top 25 million hosts or top 25 million domains of the webgraph dataset
  • a random sample taken from WAT files of the June 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://commoncrawl.s3.amazonaws.com/ to each line, you end up with the S3 and HTTP paths respectively.
