December 2018 crawl archive now available
The crawl archive for December 2018 is now available! It contains 3.1 billion web pages or 250 TiB of uncompressed content, crawled between December 9th and 19th.
The December crawl contains page captures of 735 million 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 Aug/Sep/Oct 2018 webgraph data set
- a breadth-first side crawl within a maximum of 6 links (“hops”) away from the home pages of the top 50 million domains of the webgraph dataset
- a random sample of outlinks taken from WAT files of the November crawl
- 30 million external links sampled from Wikipedia data dumps
Archive Location and Download
The December crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2018-51/.
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.
