On Thursday, May 7, 2009, from 5:00 PM to 8:00 PM, TSO will upgrade the code on the 1st, 2nd, and 3rd floor network switches in TSRB. After each switch is upgraded, it must be rebooted. This will result in approximately 5 minutes of downtime for the network devices serviced by that switch. CoC faculty, staff, and students working in TSRB will be intermittently affected during this maintenance window.
