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.
