The file server that handles computational workloads has been under severe load the last few days, and has become unstable as a result. We are currently working that machine.
We will start a reboot shortly (9:40am), which will take a bit to complete.
11:05am: the computational file server is back online and serving files as expected.
2:00pm: there is still occasionally slowness from this server, which we are investigating.
Thursday, April 6: the computational file server has stabilized.
