The crawl archive for January 2017 is now available! The archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2017-04/. It contains more than 3.14 billion web pages and about 250 TiB of uncompressed content.

Data Type File List #Files Total Size
Compressed (TiB)
Segments segment.paths.gz 100
WARC warc.paths.gz 57800 53.95
WAT wat.paths.gz 57800 20.34
WET wet.paths.gz 57800 8.97
Robots.txt files robotstxt.paths.gz 57800 0.10
Non-200 responses non200responses.paths.gz 57800 0.56
URL index files cc-index.paths.gz 302 0.21
Columnar URL index files cc-index-table.paths.gz 900 0.25

To extend the coverage of the crawl we

  • continued to use sitemaps to achieve fresh URLs for already known hosts;
  • added all accessible URLs from the top-million domains from Alexa (within 2 "hops");
  • again, used verified, DNS-resolvable domain names of European country-code TLDs (.eu, .fr, .be, .de, .ch, .nl, .pl, .ru, .dk), thanks to the continued donation of this data from webxtrakt.

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-2017-04/. 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.

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.

Erratum: 

Erroneous title field in WAT records

Originally reported by:

The "Title" extracted in WAT records to the JSON path `Envelope > Payload-Metadata > HTTP-Response-Metadata > HTML-Metadata > Head > Title` is not the content included in the <title> element in the HTML header (<head> element) if the page contains further <title> elements in the page body. The content of the last <title> element is written to the WAT "Title". This bug was observed if the HTML page includes embedded SVG graphics.

The issue was reported by the user Robert Waksmunski:

...and was fixed for CC-MAIN-2024-42 by commoncrawl/ia-web-commons#37.

This erratum affects all crawls from CC-MAIN-2013-20 until CC-MAIN-2024-38.

Erratum: 

Missing Language Classification

Originally reported by: 
Permalink

Starting with crawl CC-MAIN-2018-39 we added a language classification field (‘content-languages’) to the columnar indexes, WAT files, and WARC metadata for all subsequent crawls. The CLD2 classifier was used, and includes up to three languages per document. We use the ISO-639-3 (three-character) language codes.
