Update: the spine switch has been installed but not all cluster traffic is taking advantage of it yet. We will need to schedule another installation window in the coming weeks to finish this. For now the UC cluster is back to an operational state.
Access to Chameleon systems at UC will be unavailable from 8:00 AM CST until 12:00 PM CST on December 10, 2018 to allow for the installation of a new network spine switch which will increase the networking capabilities at UC. This will affect CHI@UC and the Jupyter notebook environment.
