Of course but that's always the case, no matter where the race is held, someone somewhere will be asleep.
Japanese figures were actually the 4th highest ever since I began tracking (if I'm not mistaken, I should move all of them to be in the same place, now they are in like 3 different files on two different machines

). Quite predictably, as
@effenberg said Americas were asleep, and thus English, Spanish and Portuguese feeds were considerably down. German feed was the only one up from Berlin (I don't have figures for LA, so I use that as a reference) again quite predictably as much of the usual viewers likely attended live.
Also what's notable that the Spanish feed hasn't reached even 1K this year (even though London for some reason set a new record for the total viewership) while they usually have been somewhere around 2K and the record is at 3800 (higher than any official feed today).
