A distributed denial of service attack last week hit UltraDNS,
the company that provides the domain name system (DNS)
infrastructure for the .org and .info top level domains, flooding
its servers with a high volume of data, according to CNET News.
It appears that the attackers sent about two million requests per second to each of the devices that connect the DNS network to the internet early on Thursday morning, during the four hours of peak activity.
According to CNET News, UltraDNS characterised the attack as the biggest they have ever seen, but said it did not affect the operation of their servers.
Last month, another denial of service attack failed to block the internet's domain name system root servers.
