Due to a networking issue at TACC, Chameleon’s portal, CHI@TACC, KVM@TACC, and CHI@EDGE are currently unavailable.
This affects site access as well as already running resources. Site networking staff are investigating, but there is no ETA
for resolution at this time.

The outage is resolved, and the object store is available again.
A rebalancing operation in the underlying storage cluster caused higher than normal I/O, and pushed some of the storage nodes into an unstable state. The node configuration has been tuned to prevent this instability from recurring.

We're currently seeing elevated error rates when provisoning nodes at CHI@UC.
When deploying an instance at CHI@UC, if it moves to state "error", with a message about "provisioning timed out", please reach out to the helpdesk, and include the UUID of your instance and node(s).
We're currently working to narrow down which nodes are affected and reproduce the issue.
