Thousands of players across the world are playing and having a good experience – in fact, more than 700,000 cities have been built by our players in just 24 hours. But many are experiencing server instability and consequently, the rollout in North America has been challenging. It's also now evident that players across Europe and Asia are experiencing the same frustration. Our priority now is to quickly and dramatically increase the number and stability of our servers and, with that, the number of players who can simultaneously access the game. We added servers today, and there will be several more added over the weekend. We're working as hard as possible to make sure everyone gets to experience the amazing game we built in SimCity.
