Hi!
The problems are ours – one of our servers ran out of disk space and that caused a knock-on effect that we’re still working to recover from. Sit tight, once we resolve the problems, we’ll re-generate the missing playlist. And soon we’re going to add two more servers to separate data dump generation (super disk space intensive) from the rest of the production systems.
And thanks for the lovely feedback about the playlists – when we first starting working on this we had a lot of negative feedback “recommendations will never work!”, but we kept pushing on. We ended up learning something important: Recommendations are not that hard if you’re actually not trying to recommend crap the user doesn’t want to listen to. (looking at you spotify!)
