Sunday, February 14, 2016 between 5:00 AM – 7:00 AM, Cornell IT will be upgrading the core routers on campus to improve campus network connections. During this time there may be intermittent interruptions in connections to the wired and wireless networks on campus. Although the ECCO and SDS computing systems will continue to operate, and jobs continue to run, access to the systems will be unavailable during the core router upgrade. Please plan accordingly.
