do servers restart on a schedule? I only noticed it restarted when there was 1 minute left.
otherwise, I could only assume they would post somewhere if there is impending downtime, and how long it would be expected for... a quick google search found nothing, twitter was my first go-to, however nothing about downtime was posted there... please let me know where such status information could be found - again, I can only assume its found somewhere, even small indie developers tend to keep their player base informed about such things.
There are messages in game for half an hour beforehand
