"The task may finish ahead or late of schedule depending on the actual situation."

Per previous replies in this thread, there was a delay in Servers being taken down for the scheduled Maintenance, naturally this pushes back the time slot for the Servers to be reinstated.

I believe it was something like up to 90 minutes behind due to unforeseen cir*stances, but I'm sure they're working hard to get the Servers back up & running so we can get back to our oh so highly addictive game.
