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.

Update July 6th: Reservations for floating IPs at CHI@TACC should work as normal now.
Update: July 5th
Reservations for Floating IPs at CHI@TACC are still failing, and we are working on a fix.
This only affects reservation for a floating IP. You can work-around this issue by not reserving IP addresses, and using ad-hoc IPs instead. You can find instructions for this method here: https://chameleoncloud.readthedocs.io/en/latest/getting-started/index.html#associating-an-ip-address

We discovered an issue preventing DHCP from working when provisioning nodes, this has now been resolved.
If you saw error messages like:
Exceeded maximum number of retries. Failed to provision instance <uuid>: Timeout reached while waiting for callback for node <uuid>
or that the instance simply failed to start after a long while at TACC during this time, please try again, as this may have been the cause.

Update: 06/15/2022:
Provisioning of new instances at UC is now functional with all the Chameleon supported images available.
Unfortunately, we were not able to restore all of the images. We are still in the process of restoring some of them and will be contacting users whose images have not been possible to restore and working with them through available options. If you don’t find the image you are looking for, please reach out to help desk.
