OSCER users,

The new home storage subsystem will be down for ~1 hour
for a software upgrade. We hope to have it back in production
later this morning.

As always, we apologize for the trouble -- our goal is to make
OSCER resources better!

OSCER users,

We need to reboot one of our /home servers.

Some users might experience job failures and/or login failures.

Once it's back in production (well under an hour), please
check whether any of your jobs have failed, and if they have,
please resubmit.
