It includes page captures of 1.0 billion URLs not contained in any crawl archive before. The other 1.5 billion pages have been already captured in prior crawls and are now revisited.

Archive Location and Download

The September crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2019-39/.

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.
