AirwaySim's web services will be moved to a new server hardware next week. The preliminary date for the move is Thursday 7th December (in the afternoon EU time), but this might still change. During the move you can expect a short (< 1 hr) downtime of the services, with games being paused at that time. This change is part of the general all-around upgrading and rationalization of company's server hardware, and also brings in more computing capacity to the backend services of the simulation.
