mC4 is an awesome and very meaningful project—huge thanks to everyone maintaining and contributing to it!

I’m looking for mC4 (or underlying Common Crawl) data from around 2008–2013, but I haven’t found a clear way to download those older years. Does anyone know if these archives exist or if there’s a recommended method to access them?

Also, I’m wondering if anyone has tried to fill gaps before 2008—for example, by combining other web archives or datasets to reconstruct earlier multilingual web content. Are there any known solutions, datasets, or workflows for this?

Any tips, links, or pointers would be greatly appreciated. Thanks!
