On Saturday the 11th of October Paligo will perform system maintenance which will result in the application becoming unavailable for no more than 1 hour. This will be scheduled depending on your region. See times below:

Europe: 8:00 PM - 9:00 PM (CEST, Stockholm)
US: 5:00 AM - 6:00 AM (EDT, New York)
Asia: 6:00 PM - 7:00 PM (JST, Tokyo)

It is recommended that you and your fellow users log out by 10 minutes before this maintenance so that draft work in progress is not lost (e.g. imports, exports and structure creation).
