At approximately 11:27AM ET on November 3, ClearlyIP's NOC team began to receive system alerts indicating excess session activity within its US-East trunking systems. The team's investigation identified unauthenticated INVITE messages being received from unknown IPs as the source of the excess traffic, as well as a customer generating unexpected levels of outbound calls. Steps were taken to mitigate the traffic's impact, including restarting affected services to clear sessions and restore normal status. By approximately 11:55AM ET, the US-East situation was stabilized and session traffic had returned to normal levels. The team has identified a number of improvements and traffic management strategies to help avoid similar incidents which will be implemented in future maintenance events.
