March 2023

The email server upgrade scheduled for this morning has run into unexpected issues. As a result, email service is not working properly. We are working to correct the situation as quickly as possible, and will update here as new information becomes available.

Update 08:57 – We continue to work to recover the mail systems, but they will not be ready in the original scheduled window. We apologize for the inconvenience.

Update 10:02 – We are working with the vendor to recover the mail systems. We apologize for the inconvenience.

Update 15:18 – We now believe the service is back to normal operation. Most incoming emails were likely queued and have probably been delivered by now. If you have ongoing issues, please reach out to CS Staff. Thank you for your patience!

Today is the day for this scheduled power shutdown. Please see the below announcement and remember to power down and unplug any and all equipment you control in the CS Building or Friend Center before ending your day today!

Thanks for your time and attention.

Sincerely,
CS Staff

Subject: [downtime] CS Building Power Outage, Monday, March 13, 2023, 22:00-02:00

Date: Monday, March 13, 2023 (22:00-02:00)

Who is affected:
ALL users and occupants of the CS Building (35 Olden St) and Friend Center

What is happening:
From 22:00 (10PM) until 02:00 (2AM) on the night of Monday, March 13, 2023,
ALL power to the Computer Science building and the Friend Center will be
cut.

Emergency generator power will remain, so emergency lighting and the
building network will remain powered. ALL OTHER POWER will be off. It is
VERY IMPORTANT that all equipment, including that in labs and in Room 002,
be powered off on Monday evening prior to the shutdown. This includes
computers, printers, copiers, or anything else that runs on electricity.
Sensitive equipment will further benefit from being unplugged or physically
switched off in order to avoid any effects from possible fluctuations in
power quality during the work.

Why is it happening:
In August of 2022, a sprinkler head in the basement power vault opened,
flooding the main power feeds for the building with water and causing
damage to a main breaker. Since that time, the building has been operating
on a single breaker from a redundant set while the damaged breaker was sent
away for repairs. This outage will be used to re-install the repaired
breaker and return the building to normal operating status. Until this
repair is completed, the building power is more vulnerable than usual to a
long-term outage in the event the single remaining breaker is compromised.

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

Note that this outage DOES NOT affect the CS computing infrastructure,
which is housed in the Forrestal Campus data center. All departmental
computing and network services are expected to continue unaffected.

If you have questions or concerns about this outage, please contact
csstaff@cs.princeton.edu immediately, so we can discuss options to reduce
any negative impact. Your patience is appreciated.

Sincerely,
CS Staff

Date: Thursday, March 16, 2023 (07:00-09:00)

Who is affected:
Users of CS Department email services

What is happening:
During this window, the CS Department email servers will be upgraded. The
actual outage for any given account will be relatively brief, but the
overall work may be longer. The outage for any particular account may occur
at any time during the scheduled window.

The expected outage behavior is that you may be unable to read email on
your account for several minutes. Sending email may also be interrupted for
some configurations. If you find your account behaving strangely, wait a
few minutes and reconnect or reload, which should reestablish expected
behavior.

Why is it happening:
This upgrade will apply security and maintenance updates to the mail
servers as part of routine system hygiene.

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
