[downtime] CS Network Maintenance, Wednesday, October 13, 2021,

Date: Wednesday, October 13, 2021 (07:00-08:30)

Who is affected:
Users of CS Department Network Services

What is happening:
The CS Department’s network uplink to OIT’s network (and onward to the
internet) will undergo configuration changes in preparation for deployment
of OIT’s Next Generation Network.

No noticeable outage is anticipated, but as technological changes always
present the possibility of unexpected results, this message is notice in
case of the unexpected.

Why is it happening:
This change will enable router peering with OIT’s new routers in the Lewis
Library and New South buildings, providing more redundancy than the
original design which uplinked the department only through Lewis Library
(and 87 Prospect prior to that).

This is the second step in a multi-step process of reconfiguring this
uplink.

We will post updates to the status page: http://www.csstaff.org
as necessary.

If this work will cause you undue hardship, or if you have questions or
concerns, please contact csstaff@cs.princeton.edu to discuss. Your patience
is appreciated.

Sincerely,
CS Staff
