[Sunday, 12h00 GMT+1] Everything back to normal! Download speed is now around 1250 per minute. This is anyway quite high compared to the June-October period, where it almost never went above 800 downloads/minute. I had one visitor of Singapore the minutes after publishing the post at 10h30 GMT+1: indeed Asia was still awake! But i am wondering why this sudden and very temporary increase!
