The TerrorTime servers seem to be completely operational again. Make sure to connect using the newest version of terrorTime.apk. Version 1 wasn't always able to connect, particularly when the server had many users. Version 2 should be able to connect more reliably. You can find the download after completing Task 1 or Task 2.
We've heard through SIGINT "chatter" that the terrortime chat servers are undergoing maintenace. You may have difficulty connecting with the TerrorTime application during this time.
