Improvements and Fixes

The HTTP headers in WARC response records have been fixed: the HTTP response status line now has a white space following the status code if the reason-phrase is empty. E.g., if a server sends an empty message (instead of “OK”), the status line will include a trailing space character: “HTTP/1.1 200 ”. Following RFC 7230 the white space between status code and message is mandatory. Please refer to the bug report NUTCH-2763 for further details.

Archive Location and Download

The February crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2020-10/.

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-2020-10/. 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

Originally reported by: 
Robert Waksmunski
Permalink

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.
