Date: Thursday, August 31, 2017 (07:00-09:00)
Who is affected:
All users of the CS Staff-managed public login systems, including the
cycles and courselab systems.
What is happening:
During this window, these systems will have their OSes reinstalled and
upgraded to the latest distribution version, Springdale 7.4.
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
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
