Thank you for your patience. We rebooted the failed switch, recovered it from backup and things are now accessible again. If you find any issues please place a ticket at https://helpdesk.fau.edu/
10 pm February 10, 2020: A network switch failure in the HPC data center has caused numerous (most) HPC cluster services on Koko to fail. We will be rebooting and reseting the switch in the morning and are hopeful it will come back online shortly there after.
