The crawl archive for January 2020 is now available! It contains 3.1 billion web pages or 300 TiB of uncompressed content, crawled between January 17th and 29th. It includes page captures of 960 million URLs not contained in any crawl archive before.
Improvements and Fixes
- date time values in the column "fetch_time" of the columnar index are now stored using the "int64" data type. For details and compatibility issues please see cc-index-table#7
- WARC request records now show the HTTP protocol version sent with the HTTP request which can be different from the version received in the HTTP response message, cf. NUTCH-2760
Archive Location and Download
The January crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2020-05/.
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-2020-05/. Also the columnar index has been updated to contain this 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 info@commoncrawl.org for sponsorship information.
Erratum:
Erroneous title field in WAT records
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:
- https://groups.google.com/g/common-crawl/c/ZrPFdY3pPA4/m/s5D_8wCJAAAJ
- WAT extractor: Document title bug ia-web-commons#36
...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.
