The crawl archive for April 2016 is now available! More than 1.33 billion webpages are in the archive, which islocated in the commoncrawl bucket at crawl-data/CC-MAIN-2016-18/.
To assist with exploring and using the dataset, we provide gzipped files that list:
- all segments (CC-MAIN-2016-18/segment.paths.gz)
- all WARC files (CC-MAIN-2016-18/warc.paths.gz)
- all WAT files (CC-MAIN-2016-18/wat.paths.gz)
- all WET files (CC-MAIN-2016-18/wet.paths.gz)
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-2016-18/.
For more information on working with the URL index, please refer to the previous blog post or the Index Server API. There is also a command-line tool client for common use cases of the url index.
Note that the April crawl is based on the same URL seed list as the preceding crawl of February 2016. However, the manner in which the crawler follows redirects is changed: redirects are not followed immediately; instead redirect targets from the current crawl are recorded and followed by the subsequent crawl. This approach serves to avoid duplicates with exactly the same URL contained in multiple segments (e.g., one of the commoncrawl.org pages). The February crawl contains almost 10% such duplicates.
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 and packages.
