Current State of Minimum

Complete server outage
Minimum's servers have been down since 09/30/2015. Initially, it was announced that the issues should be resolved within a few days. However, after a week the developers wrote in a further announcement that an essential third-party middleware had been discontinued, but promised that a solution will be found. At this point, users were unable to buy Minimum on Steam.

After no communication with the community whatsoever for two months, the re-release date was set for early 2016.

On 02/17/2015, the developers announced a solution for the issue and a re-launch of the game "within the next few weeks", probably around March. The concept of privately hosted servers has been dropped, and in the future, players will be able to host game sessions.

Error message associated with the server outage
The error message appears right after starting Minimum and reads "Invalid Mber username or password."
