Assault on Net servers fails

PDT Monday, and as of Tuesday afternoon, Michael Kors handbags cheap it appeared to be continuing, according to Matrix NetSystems, an Austin, Texas, company that measures Internet performance.

Traffic from several Internet service providers has been slightly delayed, but because the domain Michael Kors handbags cheap name system, or DNS, is spread out and because the 13 root servers are the last resort for address searches, the attack had almost no effect on the Internet itself.

“There was never cheap michael kors an end user that said there was a problem,” said Paul Vixie, chairman of the Internet Software Consortium, a group that supports the open source software on which many domain name servers run.

The group also administers one of the Michael Kors handbags 13 computers specifically, the “F” server that routinely match Internet addresses. The system also works in a layered manner, so that someone who wants to go a specific address is first directed to a local server. Most requests that the ISC’s “F” server sees, Vixie said, are from poorly designed networks that don’t cache earlier answers to requests for information.

“We answer a request and then two milliseconds later get another request from the same user for the same domain,” he said.

The “F” server responds to more than 270 million domain name service queries each day, according to its Michael Kors handbags cheap site.

While Vixie took issue with reports that the attack had been the “largest ever,” he did say cheap michael kors that aspects of the data flood made it unusual. “There have been (previous) attacks against the root domain servers yes,” he said. “But it is rare to have attacks against all 13 at the same time.”

Still, cheap michael kors outlet the results were not severe. The attack, at its peak, only caused 6 percent of domain name service requests to go unanswered, according to Matrix NetSystems. The DNS system normally responds almost 100 percent cheap Michael Kors handbags of the time. Army Research Lab in Aberdeen, Md.; the “I” server, located in Stockholm; the “K” server, located in London; and the “M” server, located in Tokyo.

About 4,000 denial of service attacks hit the Internet in the average week, according to data collected michael kors handbags outlet by the Cooperative Association Michael Kors handbags for Internet Data Analysis. Many of those are aimed at domain name servers.
