Whatever the hell "internal production problem" is. It's probably just a funny way to spell "some dingus thought it would be fun to mess with our stuff seeing as it's Guy Fawkes Day and all."
After hearing the news that The Daily, part of News Corp and thus, within the wrinkly-handed reach of news tycoon and journalist ultra-douche Rupert Murdoch, staff at the company made a little ditty to the tune of "So Long, Farewell" from The Sound of Music. All I have to say is mad props for actually putting that together. If I were in their position, I would have been out the door faster than you can say "auf wiedersehen."
