Akamai Technologies Inc. acknowledged Wednesday that a "sophisticated, large-scale" distributed denial-of-service attack occurred that targeted several of the distributed computing service provider's customers.
However, Akamai says the impact of the attack on specific Web sites has been "inaccurately portrayed." The company also wrote in a statement that the attack impacted the domain name service requests for roughly 4% of Akamai's customer based, but only 2% of its customers had any noticeable impact, and just 1% of its customers experienced "significant impact" of Web-site performance, which the company estimates affected 20% of Web surfers who visited those sites.
Web performance monitoring company Keynote Systems Inc. reported on Tuesday that Apple, Google, Microsoft, and Yahoo suffered performance degradation which began around 8:30 a.m. EDT and continued through 10:45 a.m. EDT.
A Microsoft spokesman says the company hasn't received reports from customers related to any Web-site outage.
