This outage is now resolved, CHI@UC appears to be working as normal.
We don't yet have a root cause from our provider, but are working with them to prevent a repeat.

Resolved: Jupyter service should be working as normal.
Update: We are waiting on DNS updates to finish the updating of our Jupyter infrastructure, and so the outage is ongoing. Thank you for your patience.
We will be updating our Jupyter infrastructure on the morning of Monday, March 3, which will take down JupyterHub and running JupyterLab instances.

Resolved: Work has been completed.
TACC network infrastructure will not be available from 6:00AM to 7:00AM (CDT) on Wednesday, February 19 2025. Network maintenance will be performed during this time. This will impact access to the Chameleon Portal, JupyterHub, CHI@TACC, KVM@TACC, and CHI@Edge. Experiments and VMs will continue to run, but will not have connectivity outside of TACC.

Resolved: Instance launches on KVM@TACC are once again working.
Some users are experiencing the message "not enough hosts available" when attempting to launch an instance on KVM@TACC. Staff are troubleshooting the problem.
| Outage start | Wednesday, January 22, 2025 1 p.m. |

| Expected end | Tuesday, January 28, 2025 6 p.m. |
The Jan 28th maintenance window has concluded, and KVM@TACC is back to normal.
We were able to migrate the loadbalancer and database services to a redundant configuration, but had to roll back the migration of other control-plane services due to unforseen complications. We'll be investigating a path forward, and a subsequent (shorter) maintenance window to finish the migration for each service.
| Outage start | Thursday, December 19, 2024 9:30 a.m. |
| Expected end | Thursday, December 19, 2024 10:15 a.m. |
On Thursday, December 19 at 9:30 am CT, Chameleon's authentication service and Trovi will be down for network maintenance. During this time, users will not be able to access the Chameleon sites (CHI@UC, CHI@TACC, KVM), or authenticate to the user portal. Running nodes will be unaffected.
| Outage start | Thursday, December 05, 2024 1:20 p.m. |
| Expected end | Thursday, December 05, 2024 6 p.m. |
We're receiving reports of issues reaching CHI@UC, but the issues seem depend on the source address, so we have not been able to reproduce them consistently.
This manifests as timeouts for horizon dashboard at https://chi.uc.chameleoncloud.org, or disconnections when connecting to instances over ssh.
We're working with our network provider to troubleshoot the issue.
| Outage start | Wednesday, November 20, 2024 3:31 p.m. |
| Expected end | Wednesday, November 20, 2024 6 p.m. |
The outage should now be resolved, but we're continuing to monitor.
Please let us know if you observe new issues connecting to baremetal nodes, or accessing shared storage.
