Ok but seriously though the actual truth is that we changed our media serving yesterday. You guys have been so good with uploading your videos to NS and watching tonnes of them, that our bandwidth usage is skyrocketing!
We needed to upgrade to some ultra-badass new servers for our media, which we did. There was some technical problem with the DNS resolving that's got the old servers cached on some computers. Paul is working on it, and will have things up and running soon!
In the meantime, go with the powder story if anyone asks.
