CHI@TACC Network connectivity

Posted by Cody Hammock on September 29, 2025
Outage start Saturday, September 27, 2025 6 a.m.
Expected end Thursday, October 02, 2025 4 p.m.

Update 10/02/2025:

KVM@TACC and CHI@Edge are now back to normal.
CHI@TACC is back to normal, exept for the following:

  • A subset of baremetal nodes that lost network configuration.
  • Composable hardware (Liqid and GigaIO) cannot reach their attached GPUs, pending a restart of these nodes and their shared PCIe backplane.

Thank you for your patience as we restore these!


Update 09/30/2025:

CHI@TACC and KVM@TACC are now passing tests for new instances.
Some older instances are still experiencing issues, we are working through the list to resolve them manually.
CHI@Edge is still experiencing failures starting new containers, and we're working to resolve those issues.


Due to a power outage the morning of Septermber 27th, the following services are encountering issues:

  • CHI@TACC: Some baremetal nodes are encountering network issues
  • KVM@TACC: Some instances are failing to power on, stuck either in state "powering on", or the console showing "booting from hard disk"
  • CHI@Edge: launching new containers is currently failing

We are working to restore this functionality.
