I find the odd part is not so much the recursive directory structure but that it stops at 13 levels, followed by a different directory. How did this happen?
Interestingly, at 39 levels deep[0], you can keep going. However, if you go to 40 levels deep[1], the link to `ubuntu` just disappears. Manually appending it to the URL to get to 41 levels deep[2] gives a 403 Forbidden response.
As for why, does anyone know? Because at 39 levels, you're well past an obvious folder path limit of 256 characters. Specifically, at 39 levels, the path portion of the URL is 273 characters (299 total). At 40 levels, it's 280 characters long (306 total). It doesn't seem like a character limit because you can still access the other folders/files from 40 levels deep.

"It's no use, Mr. Torvalds — it's Ubuntu all the way down!"
It looks like a recursion problem. Will only keep doing it until it fills up?
Haha why?
rsync at it again?
