They're adding new bugs.
That's the most hopeful sign we've seen in months.
It happened the same for me. Not sure why.
I re-installed the game 2 days ago and I keep getting the message of Error 211 every time I open the game. After that, the game start as usual.
But it's annoying.
Looks like this has been fixed now, I have not gotten errors login except for the unannounced maintenance. It was right during my fight for a fort that I should have won, came back when servers were allowing login about 15-20 min later and saw I lost and enemy got fort and timer was 0. FF was also started late with unannounced maintenance.
I would be nice to have alerts so we can plan for maintenance. Although any maintenance is appreciated.
