Reported Outages

REMINDER:

Dear Chameleon users,

We have received short notice from the building that they will be performing power work in the datacenter housing the CHI resources at the University of Chicago on Monday, May 9th 2016.

CHI@UC will be unavailable starting at 08:00 AM CST. Work is expected to last approximately 12 hours plus recovery time on our end. An all clear message will be sent out once the work has been completed.

NOTE: Instances may not be available after the maintenance period. We recommend that you snapshot your work ahead of time.

Update: The work has been completed.

In order to apply routine software updates, the Chameleon virtualization cluster at TACC (KVM@TACC) will be unavailable on Tuesday March 1, 2016 from 7:00 to 9:00 AM Central Time. During the work all API endpoints, the dashboard, and networking will be unavailable. Instances are not expected to be interrupted, but will not be accessible.

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.
