Who is affected:
All users of the CS Department computing infrastructure, including web
servers, public login and cluster servers, file service, and more.
What is happening:
The file server supporting most CS Department computing services will have
its OS and server software upgraded. During this time, all public login
servers and the ionic cluster will be shutdown and rebooted in order to
minimize the risk of data corruption or loss.
Why is it happening:
This upgrade is part of the regular maintenance of our storage system, and
is expected to improve the performance of the system.
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
