At approximately 1:40 PM today, we experienced a network outage. As is customary, our network staff began diagnosing the problem and made an initial call to our internet connection provider, the Connecticut Education Network (CEN). The CEN Helpdesk informed us that they were not aware of any network issues.
Diagnosing the problem was extremely difficult because our network devices where so overwhelmed with incoming network traffic that our network staff were unable to get access to them. They restarted the devices, only to see them immediately become overwhelmed and unresponsive again. This pointed to a Denial of Service (DOS) attack on our network.
