AirwaySim's web server system will be upgraded soon. Our current setup has served us well and since it has been in use from winter 2013 it is already good time to retire that hardware. This upgrade allows us to give you the best possible service and to develop better features in the future too (by increasing the calculation capacity). At the same time we will also switch our ISP (service provider) since the support and services from current ISP (Nebula) have not been satisfactory. Our new servers will still be located in Finland (like already currently), and we will continue to use own dedicated hardware for best capacity and configurability. Since some of the testing and setup work is still in progress no exact time / date has been set for the upgrade but plans are to do it by the end of this month. During the upgrade all games will be paused and website will be unaccessible for approximately 2-4 hours. We will inform you all a few days prior of the exact time of this maintenance window. This is a pure hardware upgrade so there will not be any feature changes or updates. All of the background systems like database engines and other such sofware will be updated but these are not visible to users. The next new game worlds (apart from normal rotation of Beginner's World) will begin after this upgrade is complete.
