RE: Update: Core Router Replacement Project on Hold

Dear UCSB IT Colleagues,

On February 5, 2020, work began to upgrade the UCSB Core Network with 10 new Cisco core routers across seven campus locations, with completion expected in May 2020.

Please see the revised schedule below. We rescheduled HSSB - Building 515 and Physical Sciences North - Building 657 for May. 

This work is the first of a multi-stage effort to reconfigure UCSB’s network into a multi-layered network. Work will mostly occur overnight and may include network outages for up to three hours. One outage will be scheduled during work and class time, but it should not impact the public. 

We will publish announcements prior to each scheduled outage, along with a list of buildings that may be impacted. Please note that services hosted within affected buildings will be unavailable during the outage.

The physical core router replacement will affect the locations below on the following tentative dates:

  • North Hall - Building 535 
    • The first router was installed on Tuesday, November 12, 2019
    • Complete, no public impact
  • Public Safety - Building 574 
    • Wednesday, February 5, between 9 a.m. and noon
    • No public impact expected
  • Noble Hall - Building 544 
    • Wednesday, March 25, between 3 and 6 a.m.
  • Harold Frank Hall - Building 556 
    • Wednesday, April 1, between 3 and 6 a.m.
  • Public Safety - Building 574 
    • Wednesday, April 8, between 3 and 6 a.m.
  • North Hall - Building 535 
    • Wednesday, April 15, between 3 and 6 a.m.
  • North Hall - Building 535
    • Wednesday, April 22, between 3 and 6 a.m.
  • Portola - Building 1861
    • Wednesday, April 29, between 3 and 6 a.m.
  • HSSB - Building 515 
    • Wednesday, May 6, between 3 and 6 a.m.
  • Physical Sciences North - Building 657 
    • Wednesday, May 13, between 3 and 6 a.m.

Updates will be provided via this list, D-list, at it.ucsb.edu, status.ucsb.edu, and at the UCSB IT LinkedIn, Facebook, and Twitter pages. You can subscribe to status.ucsb.edu to receive notices of service-impacting events at UCSB.

The new core routers, part of UC Santa Barbara’s Next Generation Network program to invest in the campus data network infrastructure, will enable intra-core connections at 100Gb and building connections up to 25 gigabytes. This will create a more robust and reliable campus network that allows for higher internal traffic processing and enables the next generation of teaching and research.

Thank you for your patience as we undertake this initiative.
