I'm happy to announce that we are upgrading DF2's servers tomorrow. These much more powerful machines should make the game a lot more responsive and improve stability when higher numbers of players are online. However in order to complete this upgrade it will be necessary to take the game offline for up to 4 hours.
The servers will be turned off on Wednesday 13th at 7pm UST (3pm EST) and we expect this downtime to last anywhere from 2 to 4 hours. If for some reason it takes any longer than this we'll keep you all updated via our Discord.
