On Wednesday (July 9), following an attempt to upgrade the campus Internet connection, the University experienced periods when the Internet was not available. During these periods, users on campus could not access the Internet, and users off campus could not access campus services, such as the campus Web site, email and Banner. These Internet outages occurred throughout the day on Wednesday (July 9) and recurred briefly Thursday evening (July 10).
Technicians from University IT Services (UITS), Cisco, and BlueCat were on campus throughout this incident, and have identified the source of the problem as a newly discovered software "bug" in the network management software used by the University. The software module responsible for this problem has been temporarily disabled. This has restored Internet service for the campus.
This evening (Friday, July 11) the software vendor has released a software patch to correct this problem. UITS is testing this patch. Once the patch has been successfully tested, UITS will apply the patch to the network management system. UITS is also rescheduling the campus Internet upgrade for sometime next week.
