Improvements and Fixes

  • date time values in the column "fetch_time" of the columnar index are now stored using the "int64" data type. For details and compatibility issues please see cc-index-table#7
  • WARC request records now show the HTTP protocol version sent with the HTTP request which can be different from the version received in the HTTP response message, cf. NUTCH-2760

Archive Location and Download

The January crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2020-05/.

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-2020-05/. 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 info@commoncrawl.org for sponsorship information.
