In the past three years, Akamai has seen 2,000% increase in the number of DDoS attack incidents investigated on behalf of its customers. The latest State of the Internet report released today by Akamai also identifies top countries from which this observed attack traffic originates, as well as the top ports targeted by these attacks.

From the report: During the third quarter of 2011, Akamai observed attack traffic originating from 195 unique countries/regions, up from 192 in the second quarter. After making its first appearance in the top 10 list in recent memory in the second quarter, Indonesia vaulted to the top of the list this quarter, generating 14% of observed attack traffic. Myanmar, which had suddenly appeared at the top of the list in the prior two quarters, disappeared from the list just as suddenly in the third quarter, potentially indicating that the attack traffic that had been observed originating from the country has either been shut down, or is now coming from other places. With Myanmar dropping out of the top 10 list, South korea moved into it, more than tripling its observed level of attack traffic, responsible for 3.8% in the third quarter. In addition to South korea and Indonesia, Taiwan, China, India, and Egypt were all responsible for higher percentages of attack traffic as compared to the prior quarter.
