Owens login nodes are impacted due to switch replacement on Thursday, Jan 17, 2019

We will perform the replacement work of Ethernet switches from 12pm to 3pm on Thursday, Jan 17, which includes all login nodes and 2 quick nodes on Owens. As a result, users won't be able to log into Owens at the beginning and end of the maintenance work, and won't be able to use Owens VDI through OnDemand during the entire maintenance window. Running jobs on Owens, as well as other OSC services (Pitzer, Ruby, and fileystems) won't be impacted. 

We apologize for any inconvenience this may cause you. Please contact oschelp@osc.edu if you have any questions.
