Hyp and Q: Would it be possible to get the Leaderboard back?

Hypnotik: Those links are both showing up-to-date info for me still. You might be having a cache-ing issue if the data is out-of-date.
To confirm, check the "time" field, it's at the first level of the array ( json['time'] ), this will give you a unix timestamp of when the data is from. If that timestamp isn't current, CTRL+F5 the data (if grabbing it from a browser).
