Access to the main file server is intermittent. We're working on it now.
10:17pm Update: File system services to user home directories and project directories are now working again.
There will need to be a scheduled outage (perhaps more than one) to deal with additional clean-up and adjustments. The system might be a bit slower than usual for a few days.
Most machines have recovered on their own from the outage, but a few may be so confused they need a reboot. We'll be checking hosts, but please let us know if you run into any stuck machines.
