The crawl archive for May/June 2023 is now available! The data was crawled May 27 – June 11 and contains 3.1 billion web pages or 390 TiB of uncompressed content. Page captures are from 44 million hosts or 35 million registered domains and include 1.0 billion new URLs, not visited in any of our prior crawls.
Archive Location and Download
The May/June crawl archive is located in the commoncrawl bucket at crawl-data/CC-MAIN-2023-23/.
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 see accessing the data for detailed instructions.
Erratum:
WAT data: repeated WARC and HTTP headers are not preserved
Repeated HTTP and WARC headers were not represented in the JSON data in WAT files. When a header was repeated adding a further value of that header, only the last value was stored and other values were lost. This issues was fixed with CC-MAIN-2024-51, see ia-web-commons#18. All WAT files from CC-MAIN-2013-20 until CC-MAIN-2024-46 are affected.
Erratum:
WARC revisit metadata records
The revisit records in the Common Crawl WARC archives in all crawls from CC-MAIN-2018-34 to CC-MAIN-2024-46 (since Aug 2018) lack the metadata record which is attached to all response records. Fixed with CC-MAIN-2024-51, see commoncrawl/nutch#33. Note: before CC-MAIN-2018-34, WARC revisit records were not stored at all.
Erratum:
Some 2–Level CCTLDs Excluded
A bad configuration was checked into our exclusion list on Sep 22, 2022 and was fixed on Oct 27, 2023. The configuration blocked a number of 2–level domains, meaning they were not included in certain crawls.
The excluded CCTLDs were:
We apologize for this mistake, and that it took us a while to find it.
