The crawl archive for December 2017 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2017-51/. It contains 2.9 billion web pages and over 240 TiB of uncompressed content.
To improve coverage and freshness we added 650 million new URLs (not contained in any crawl archive before)
- sampled from sitemaps if provided by any of the top 80 million hosts taken from the Aug/Sept/Oct 2017 webgraph data set
- found by a side crawl within a maximum of 4 links (“hops”) away from the home pages of the top 25 million hosts and domains
- a random sample take from WAT files of the November crawl
- and the continued donation of URLs from mixnode.com
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-2017-51/. 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.
We are grateful to our friends at mixnode for donating a seed list of 300+ Million URLs to enhance the Common 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@example.com for sponsorship information.
