EA has updated SimCity to version 1.4, and this forum post has the patch notes. Meanwhile, SimCity Update #2 from Lucy has the latest from Maxis on adding server capacity, apologizing for downtime invoked as original servers are taken offline one by one as part of an upgrade process. Finally, EA's SimCity account tweets about the possibility that they will eventually remove the online requirement for the new SimCity to earn back gamer's trust following its unsuccessful launch, though this won't be right away (thanks nin). Word is:

We have no intention of offlining SimCity any time soon but we'll look into that as part of our earning back your trust efforts.
