Network maintenance will be carried out between 10:00 AM and 4:00 PM (CST) on Sunday, November 28. Access to all TACC systems (CHI@TACC, KVM@TACC, and Chameleon Portal) will be unavailable during this time. Instances will continue to run, but users will have no access to TACC-based services and systems until the upgrade is complete.

Update: The outage is now over. Jupyterhub, Trovi, and CHI@UC are now available.

Important Note: Instances created prior to the outage are available, but must be powered back on manually. You can do so via the web ui, or other CLI / API as you prefer. They were shut down prior to the outage to avoid any data-loss.

There will be a total outage for the CHI@UC site 6pm, Friday November 19th - 12pm, Monday November 22nd, due to maintenance on the power system in the data center.

Due to a certificate expiration, the authentication system for the Chameleon sites is effectively online, preventing web and CLI-based logins. This affects all Chameleon sites, the user portal, and the Jupyter environment.

We are working with the team providing the certificate service and will update when it is back online.

Update 3:35pm: Access has been restored. Please let us know if you continue to see issues.

The chameleon Jupyterhub is currently not accessible, as of ~2:40 PM today.

We believe the cause to be related to a network configuration change, and are investigating.

We'll update here with an ETA or resolution.
