From the game banner:

We wanted to give you a heads up that tomorrow (02.04.2018) at 07:00 AM UTC we will be entering maintenance. Expected maintenance time is a minimum of 8 hours, but we'll keep everyone updated on how that will be working out. Compensation will be given out after the maintenance or the next day!

I think they meant 03.04.2018.

8 hours?! That's so long
I'm guessing we're getting a huge update then

i hope the next event is the one im thinking of

8 hours?! I thought the next Mega update was still another week away. Guess they were able to move the schedule ahead a bit then.

HEY!

They already have disabled the whaleship missions!!

Maintenance starts in one hour. If you have things to do in the game now is the time to do it.

I would be burning stamina on whaleship missions, but...
