The crawl archive for May/June 2020 is now available! It contains 2.75 billion web pages or 255 TiB of uncompressed content, crawled between May 24th and June 7th. It includes page captures of 1.2 billion URLs unknown in any of our prior crawl archives.

Starting with this crawl the WET files indicate the natural language(s) a text is written in. The language is detected using Compact Language Detector 2 (CLD2) and was made available since August 2018 only in WARC and WAT files and URL indexes. It is now also provided in WET files in the WARC header "WARC-Identified-Content-Language". Up to three language(s) are detected per document and given as comma-separated list of ISO-639-3 codes, here one example WET record fragment:

...
WARC-Identified-Content-Language: isl,eng
Content-Type: text/plain
Content-Length: 10494
