No worries!<br>

Gah, I compressed the file using xz and somehow included the wrong link.<br>
In fact, I'm surprised the link I gave you even worked, probably some<br>
Apache magic at play. You can either rename the file to<br>
recommended.csv.xz or download it using the correct link:<br>
<br>
<a href="https://people.torproject.org/~karsten/volatile/recommended.csv.xz" rel="noreferrer" target="_blank">https://people.torproject.org/~karsten/volatile/recommended.csv.xz</a><br>
<br>
Hope this works better. Sorry for the confusion!<br>
<br>
All the best,<br>
