Archive Location and Download

The May crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2021-21/.

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-2021-21/. Also the columnar index has been updated to contain this crawl.

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 [email protected] for sponsorship information.
