Throughout the morning, DYN has released statements indicating that the issue has been resolved only to have the servers crash within the following hour. Without inside information, two hypotheticals exist to explain the heat map and the disruption. First, it is possible that DYN mitigated the DDoS but has since been overwhelmed by the sudden influx of user traffic. The disruptions on the West Coast and in other countries would be due to server overload caused by DYNs attempts to balance their traffic without the targeted East Coast servers. Second, and more indicative of the following information, it is possible that DYN has been hit with multiple waves of increasing DDoS traffic in a sophisticated multi-layered attack meant to probe their defenses.
