Computer Science Status

Date: Thursday, March 27, 2025 (07:00-08:00)

Who is affected:
Users of CS Department IMAP/Pop/Webmail/SMTP services

What is happening:
Sometime during this window, CS email services will experience a brief
outage while the underlying LDAP service is reconfigured. The actual outage
time is expected to be less than 5 minutes, but the larger window is
scheduled to allow for the unexpected.

Why is it happening:
This outage will allow us to begin the longer process of updating our
Zimbra mail servers to the latest available software release. This is a
necessary first step that is intended to avert a much longer outage later
in the process, by enabling a live upgrade of the rest of the system.

No visible changes are anticipated until after the end of the semester, but
minor systems will be updated before that time to prepare for the major
upgrade in the Summer.

We will post updates to the status page: 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
