The crawl archive for March 2018 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-13/. It contains 3.2 billion web pages and 250+ TiB of uncompressed content, crawled between March 17th and 25th.
The March crawl contains 800 million new URLs, not contained in any crawl archive before. New URLs are “mined” by
- extracting and sampling URLs from sitemaps if provided by any of the highest-ranking 100 million hosts taken from the Nov/Dec/Jan 2017/2018 webgraph data set
- a breadth-first side crawl within a maximum of 3 links (“hops”) away from the home pages of the top 60 million hosts or top 30 million domains of the webgraph dataset
- a random sample taken from WAT files of the February crawl
- and the continued and increased 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://commoncrawl.s3.amazonaws.com/ to each line, you end up with the S3 and HTTP paths respectively.
