New L-Root DNS Server Enhances DNS Fault Tolerance and Resistance to DDoS Attacks

18 May 2012

A new instance of L-Root has been installed in Odessa, Ukraine, increasing the Domain Name System's (DNS) overall fault tolerance and its resilience against certain types of cyber threats, such as Distributed Denial of Service (DDoS) attacks.

The launch of the server node is a joint operation between ICANN and Ukrainian domain registry Hostmaster. DNS Root Servers form a key part of the Internet infrastructure that contribute to the global security and stability of the DNS.

"Odessa is one of the largest Ukrainian cities, with one of the highest Internet penetration rates in the country," said Dmitry Kohmanyuk, a Hostmaster official. "Moreover, the Internet provider we opted for has quality connections to Western Ukraine, which is precisely why we decided to deploy the node there."

Hostmaster, the Ukrainian administrator of the .UA domain, supplied the equipment necessary for the installation of the new L-Root node.

"In addition to the newest L-Root server in Odessa, two other L-Root nodes, in Kyiv and Kharkiv, were also deployed through collaboration between ICANN and Hostmaster." said Joe Abley, Director of DNS Operations at ICANN."
