The crawl archive for October 2018 is now available! It contains 3.0 billion web pages and 240 TiB of uncompressed content, crawled between October 15th and 24th.
The October crawl contains 600 million new URLs, not contained in any crawl archive before. New URLs stem from:
- extracting and sampling URLs from sitemaps, RSS and Atom feeds if provided by hosts visited in prior crawls. Hosts are selected from the highest-ranking 60 million domains of the May/June/July 2018 webgraph data set
- a breadth-first side crawl within a maximum of 10 links (“hops”) away from the home pages of the top 40 million domains of the webgraph dataset
- a random sample of outlinks taken from WAT files of the September crawl
- 15 million external links sampled from Wikipedia data dumps
Please note that the character set detection was not fully working for the first 13 segments of the October crawl – about 15% of the page captures in these segments have no charset and language assigned. More information is found in the bug report.
Archive Location and Download
The October crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-43/.
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.
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 firstname.lastname@example.org for sponsorship information.
