The crawl archive for February/March 2021 is now available! The data was crawled between February 24th and March 9th and contains 2.7 billion web pages or 280 TiB of uncompressed content. It includes page captures of 1.2 billion new URLs, not visited in any of our prior crawls.

Improvements and Fixes

The ISO639-3 code for the Hmong language was updated to "hmn" – the code "blu" used so far was already deprecated in 2008. Crawl archives prior to this crawl will still use the code "blu". More details about this update are found here.
