Update: Scheduled maintenance is complete.
Access to all TACC systems will be unavailable on Sunday, 15 March, 2020 from 9:00 AM CDT until 12:00 PM CDT. This is to allow for upgrades to the TACC core network hardware. During this upgrade, users will have no access to CHI@TACC and KVM@TACC services and instances, or the Chameleon Portal. CHI@UC and Jupyter will remain available.

We experienced an outage starting at Februar 22, 10AM CT at CHI@UC due to its database going down. We have since recovered the database and restored all site functionality. No data loss occurred. This should not have affected connectivity to running experiments. However, CHI@UC and the Jupyter environment were effectively down.

Apologies for the short notice, but we must perform a short maintenance on the CHI@UC network equipment today. This will cause a brief (10-20 minute) outage on the CHI@UC site, affecting external connectivity for all experiments as well as the Jupyter portal.
