[downtime] CS Email Downtime, Thursday, October 22, 2015,

Date: Thursday, October 22, 2015 (06:00-08:00)

Who is affected:
All users of CS Department Email Services

What is happening:
All incoming email services will be shutdown for a brief period.

During this time, IMAP, POP, and Webmail will all be unavailable, as will
any email forwarding or filtering. All incoming messages should be safely
queued on our MTAs for delivery after the downtime.

Why is it happening:
This shutdown will allow us to move around a couple of the underlying
services supporting our email servers. This shuffle is necessary to prepare
for a major Zimbra version upgrade planned for the Fall Break time period
(more details to follow later), by retiring some older servers in favor of
newer versions that can better handle the coming upgrade.

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
