The patch notes include following updates and fixes:
• Update to the “select a server” dialog in the game launcher. This will now indicate which servers you have active cities on
Note: At the moment, it is going to be showing the icon for any server you’ve been to as a player. We’ll be updating this soon to show how many regions you have (X/10) per server. We know this is a little confusing for now, but we will improve.
• Fix issue where selection shard did not display when previously selected server is down
• We've fixed a problem where some players were getting stuck when switching shards in the server select menu
• Opened 1 new server, Antarctica
Electronic Arts has reported that SimCity's servers are now running 40 times faster thanks to added machines.
