Princeton CS Status

Date: Wednesday, June 23, 2021 (08:00-08:15)

Who is affected:
Users of CS Department Email Services

What is happening:
One of the two Zimbra mailbox servers will be rebooted. This will cause a
brief email outage for about half of CS Department email users. After the
reboot, some folks may need to re-authenticate to the email server. There
should be no loss of email; any incoming messages during the outage will
simply be queued for delivery once the server is up.

Why is it happening:
The out-of-band management device for this server has hit a fault and
become unavailable. As a result, our ability to troubleshoot the machine in
an emergency is presently restricted. This device also provides
environmental monitoring to the OS level (including temperature and power
supply status), so those functions are also not presently working. The
reboot will include a power cycle intended to restore the full function of
the hardware.

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.
Sincerely,
CS Staff

UPDATE: As of 11:55 AM Zimbra is back up and running.

We are currently experiencing issues with Zimbra Webmail. Zimbra is reporting a network error when accessing Webmail. We are working to address the issue and will post updates here.

Date: Tuesday, January 21, 2020 (07:00-09:00)

Who is affected:
Users of the CS Department mysql database service.

What is happening:
The Computer Science Department user and project database server needs to
undergo hardware maintenance for reported memory errors.

Why is it happening:
To continuously provide stable database resources for the department, the
CS user database server must be taken offline outside normal business hours
to perform the necessary corrective actions.

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.

Date: Tuesday, September 3, 2019 (06:00-10:00)

Who is affected:
All users of the CS Staff-managed public login systems, including the
cycles, courselab and armlab systems.

All users of the CS Department Beowulf high performance computing cluster,
known as ionic.

What is happening:
During this window, the cycles systems will be replaced with newer
hardware, and the courselab systems will be reinstalled and updated with
the latest distribution version of Springdale Linux 7.6. Armlab systems
will be rebooted.

SPECIAL NOTE: As we are reloading the Linux servers, all crontabs will be
deleted. If you have crontabs that you wish to persist, you will need to
back up your crontabs before the downtime, and restore them after.

Why is it happening:
This is part of regular maintenance to keep systems up-to-date.

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

the systems return to service.
