We're taking the servers down at 5:00 AM EST tomorrow (Wednesday) to bring 1.91 to live servers. We're also planning to disable the Trials of Atlantis client, so if you currently use this client, you should download Catacombs for free in order to be able to play when the servers come up again around 4:00 PM EST. Thanks for your patience everyone, and be sure to check here for updates throughout the day tomorrow!
