Well, it's on the same level as the rest:

We get 2 updates a week, most of the time they take hours.
Something like this should be verified on a test server, and when it's OK, the upgrade of the real server should be faster.

But no, they even get to change something on a no-maintenance day, and crash the game.

So yes, this kind of message reflects many things...

Ok, stop ranting, back to retry!
