Reported Outages

Network maintenance will be carried out between 8:00 AM and 2:00 PM (CDT) on Sunday, 26 March 2023. Access to all TACC systems will be unavailable during this time, including CHI@TACC, KVM@TACC, and the Chameleon Portal. Instances will continue to run, but users will have no access to TACC services and systems until the upgrade is complete.

Please submit any questions you may have via the TACC User Portal.

On April 3rd, CHI@EVL will be down while we replace the controller node. Conservatively, this should take about 4 hours before services are restored. Running instances and leases won't be modified, but will not be accessible during the outage window.

Update 5PM CT: Object store is back online via a workaround.
There will be a blip tomorrow at 1PM so we can test a permanent fix for this issue that triggered this outage.

The user portal will be down for about an hour for scheduled maintenance on 02/28.

CHI@IIT is back up, but we're still waiting for the arrival of replacement hardware. Currently, bringing the site back online requires in-person actions, and so you'll observe instability until said hardware is installed. We plan for this work to be completed by the end of this week, subject to parts availability.

COMPLETE: The work is complete. Please let us know via the helpdesk if you encounter any ongoing issues.

In order to perform some necessary network maintenance, there will be brief interruptions to compute instances for CHI@TACC and KVM@TACC.

Current status:
Stability issues are resolved, we had observed and fixed deadlocks in both container launches and lease creation, due to an upstream eventlet bug.
Public Floating IPs are now functional again. The network operated by our infrastructure provider was filtering some mac-addresses, which bridged networks from working.

We will be bringing down JupyterHub at 9:00 AM on January 5 for scheduled maintenance.

UPDATE: The upgrade is now complete. If you encounter any issues with jupyter or trovi, please let us know via the help desk 

On Wednesay, December 21st, from 10:30am - 2:30pm vlans 3300-3309 connecting CHI@UC to FABRIC will be down due to emergency maintenance on an upstream router. This maintenance was delayed from Dec 13th due to parts availability.

Resolved: Authentication for CHI@TACC has been resolved.

Starting at approximately 6:30 AM Central Time CHI@TACC has been experiencing an outage relating to authenticaion of the web interface. CLI access is not affected. Staff are working to resolve the issue.
