Friday, March 22, 2013, from 1:15 to 1:50 and from 4:00 until 4:30

Several hundred customers experienced an inability to access the Internet. Information Services utilizes private port addressing (PAT). This process allows SOM to configure hundreds of internal ports to use the same external/public IP address. The Campus intrusion prevention appliance detected a compromised system sending huge amounts of spam from the SOM network and blocked the public IP address it received, consequently blocking all of the private ports linked to that public address. It took IS time to identify the compromised system and remove it from the network.

Unscheduled Network Outage: On Tuesday, March 19th, 2013

Connectivity to resources on the SOM network was blocked for customers in 10 of the 16 buildings in which Information Services has a network presence. A switch upgrade eliminated the VMPS (VLAN Management Policy Server) service on which older switches depended. Connectivity to numerous switches was tested following the upgrade, but not every model switch was tested. The oldest switches were looking for VMPS for the VLAN assignment and there was no response. Troubleshooting took numerous hours to identify the issue; the fix required several hours of effort applying the change to all of the affected switches.
