At approximately 1:30 p.m. on Tuesday, Sept 19, part of the campus firewall became overloaded, which prevented access to services behind that portion of the firewall. As a result, enterprise systems including the K-State Student Information System (KSIS), the Financial Information System (FIS), Human Resource Information System (HRIS), ImageNow, printing in the computing labs among other applications were unavailable. Moving information (profiles) around to spread the load out allowed services to become available again.
ITS determined the root cause to be related to a test server sending an excess amount of multicast traffic. A known bug in the firewall was unable to process the increased load. We are working on additional mitigation with our vendor partner. ITS apologizes for the inconvenience.
