No worries!

Gah, I compressed the file using xz and somehow included the wrong link.
In fact, I'm surprised the link I gave you even worked, probably some
Apache magic at play. You can either rename the file to
recommended.csv.xz or download it using the correct link:

https://people.torproject.org/~karsten/volatile/recommended.csv.xz

Hope this works better. Sorry for the confusion!

All the best,
Karsten
