[downtime] CS System Downtime, Tuesday, March 15, 2016, 08:00-09:00

Date: Tuesday, March 15, 2016 (08:00-09:00)

Who is affected:
All users of the CS Department public login servers (tux and opus, aka
“penguins”) and cycle servers (soak, wash, rinse, and spin, aka cycles”)

What is happening:
During this window, these systems will be patched and updated from their
current Springdale 7.1 OS to the latest version, Springdale 7.2.

This is considered a minor update. Any resulting problems should be small
and relatively easily addressed. Since these machines are being patched
rather than reinstalled, cron jobs will remain intact.

Why is it happening:
This is part of normal maintenance of the publicly-accessible systems, and,
along with the upgrade of our HPC cluster (announced separately), will
bring our primary public computational systems into harmony running the
same versions of Springdale Linux.

We will post updates to the status page: http://www.csstaff.org
as necessary.

If this downtime will cause you undue hardship, please contact
csstaff@cs.princeton.edu immediately, so we can discuss options to reduce
any negative impact. Your patience is appreciated.
