I'm sorry, I completely forgot that the file I used was from six months ago when I wrote the blog post (and then promptly forgot to publish it). In the last half year, the number of coronavirus sequences has increased dramatically. One thing that you could do to drop the file size down is to filter for only complete and unambiguous sequences, which drops the number down from 1.6 million to ~100k [1].

Alternatively, the exact file I used for the post is available for one week here with MD5 sum 3c33c3c4c2610f650c779291668450c9 [2]. Anyone who wants the file is free to reach out to me directly (email is on site).
