Archon! 

On September 10th, 2019, Sparta: War of Empires will be updating its servers in the time interval of 10:00 p.m. to 00:00 a.m. UTC. While we should only need around 30 minutes to read the entrails and burn offerings to the gods of code, you may temporarily have trouble accessing the game. If you experience any problems, try waiting five minutes, clearing your entire browser cache, and then reloading the game.

Good luck!
