[downtime] Emergency CS Email Downtime, Thursday, May 5, 2016,

Date: Thursday, May 5, 2016 (07:30-08:00)

Who is affected:
Users of CS Department Email Services (IMAP, POP, webmail, etc.)

What is happening:
One of the two CS mailbox servers supporting the IMAP, POP, and Webmail
services will be shutdown for replacement of a defective DIMM. As a result,
users whose accounts are hosted by this server will experience
disconnection and an inability to read e-mail for a brief time while the
server is offline.

Why is it happening:
Hardware monitoring has indicated that a DIMM in this system is in a
pre-failure state and likely to fail soon. So as to avoid an unplanned
failure that may threaten the stability of the host, we are scheduling this
outage to replace the failing DIMM preemptively.

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.
