There will be an emergency down time affecting all UserVoice accounts tonight, Friday October 30th, at 11:00PDT. This unfortunately is out of our control, as our hosting provider needs to swap out a failed drive on their shelf. The outage should only be around 15-30 minutes.
Full details of this issue are available in the email below which we received from EngineYard.
We apologize for any inconvenience. Further information will be available here: http://engineyard.wordpress.com.
Thank you for your understanding,
The UserVoice Team

Subject: Emergency Shelf Replacement
There will be emergency maintenance scheduled tomorrrow Friday Oct 30th at 11:00PM PDT. Our monitoring alerted us of a failed drive in one of the disk raidsets on the shelf. The shelf has an older backplane version that may cause a cascading array failure if we swap out the drive and rebuild the degraded raid array. To reduce the risk of data loss on this system the shelf must be swapped tonight and the affected raidsets parity rebuilt.
During the raidset rebuild which will be a few hours, I/O performance may be affected. During the swap, slices on the shelf will have their IO frozen and automatically resumed once the swap is complete. The frozen IO (outage) should last 15-30 minutes but we will set a maintenance window of 1 hour.
