We were deprived of even these brief notices of maintenance work. The last such message was dated February 8, 2021. There is more and more communication.
The main chat in-game start to warning you 1h before the servers shutdown, with some big red font. Yet I m on system/society tabs almost all the time but I still catched the msg. It starts at 60min then at 50, 40, 30, 20, 15, 10, 5 then every each minute until it goes off.
A way to make it also show on System tab would be more fair I guess.
