at least tell us the schedule when it will be online and when not, will it be all (day) and (differend day) or will it be random?
We usually have a test for three days or a week or two, then switch off servers to prepare the next update. Each test is announced beforehands on our website and social pages. It also appears in news block in launcher when you open it. Next test is going to happen this Summer and includes a huge update for the MMO part - we haven't announced dates yet, but will do soon.
Oh! And we will also post a devlog about it :)
