The third phase of a "high availability" upgrade to the campus network will result in a network outage to a number of City Campus buildings on Sunday, August 3 from 8:00 a.m. to 12:00 p.m. The work is in preparation of creating a higher capacity, more fully redundant network environment.
Information Technology Services will install an additional distribution router that will increase bandwidth and redundancy to campus buildings. This is the third in a series of network distribution upgrades initiated on May 11. By the end of the summer, bandwidth to all City campus locations will double to 2 gigabits. Additional project phases will continue on both City and East campuses through next year.
By the end of 2015, UNL will increase its internet capacity through commodity vendors and connections to consortiums Internet2 and OmniPop.
All wired and wireless networking in these locations will be affected by this work unless noted otherwise. Administrative access to the following services will be impacted, but most of the following services will continue to function: Energy Management (EMCS), CCTV, Alarms, Door Access.
