Reported Outages

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.

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.

CHI@TACC has been upgraded to OpenStack Liberty, and has been restored to service.

Users who use automation should note that the network ID used when booting nodes has changed, and how has the UUID 915853fe-10c5-4dac-a402-ef1ebc53e427.

Update: The issue has been resolved.

KVM@TACC is temporarily unavailable due to a networking issue. We expect to restore availability later today.

We have reserved the entire bare-metal testbed at University of Chicago (CHI@UC) for a software upgrade from Monday, February 8 to Friday, February 12. This upgrade will bring exciting new capabilities to Chameleon users! Although we reserved resources for five days, we will release them as soon as we have successfully completed the upgrade process.

Update from 2016-01-27 00:20 UTC: The DNS issue has been resolved. Note that it may take several hours to be available through your local DNS cache server.

Due to an issue with DNS resolution, the Chameleon portal is currently unreachable. We're working on restoring access as soon as possible.

Update: At 11:45 AM Sunday 1/31/2016, the network maintenace at TACC was completed.

Network access to TACC will be intermittent from 9:00 a.m. to 2:00 p.m. (CT) on Sunday, 31 January 2016. An upgrade will be performed during this time. During the network maintenance, access to TACC resources, and the Chameleon portal will be unavailable. Resources at UC are expected to remain available.

Update: This incident is now resolved. Sorry for the inconvenience.

Since December 25th, we have been experiencing authentication issues on CHI@UC. You may be unable to log into the dashboard or access your instances. We are working on restoring access promptly.

An unexpected outage made both our Chameleon portal and the bare metal cloud at UC (CHI@UC) unavailable. They have now been brought back online.

It has come to our attention that the error that caused problems with launching new instances has also affected those that were already active. In those cases, the instance may report that it's filesystem is read-only. Rebooting instanaces should resolve the issue.
