We discovered a configuration problem related to the upgrade of CHI@TACC which meant that since service was resumed on Friday, your instances could have been scheduled on different nodes than the ones you reserved. If during the week-end you gathered experiment results that require specific hardware, you should unfortunately discard them.
While we fixed this issue, we had have to terminate all active reservations and instances.

| Expected end | Friday, February 19, 2016 3 p.m. |
Update: CHI@UC is now available as we have finished migrating services to a new server.
CHI@UC was scheduled to be unavailable for a short period of time from 08:00 AM on Thursday, February 18, 2016 in order to apply security updates and perform a small hardware maintenance. Due to hardware issues we needed to extend the maintenance.
