I’m planning on updating all hypervisors this weekend either Saturday or Sunday morning. This will require all VM’s to be shutdown. Downtime should be around 2 hours or so. This will also impact opensource.ncsa.illinois.edu (especially confluence and JIRA). Depending on how things go, I might also use this time to upgrade some of the software for opensource (jira, bitbucket, etc).
Update: All servers are back up and running. Downtime took a little longer due to the fact that a physical reboot was needed of the servers, requiring me to get to NCSA first.
