DeNIC DeNIC: New DENIC name servers are showing effect
After inauguration of the new servers - among other places one in Tokio and two in the USA - the response times for DE domains were decreased dramatically. User in Asia, North America and from the Pacific area are gaining most. This was shown by measurements of the Japanese domain register authority JPRS and the DENIC. Recently Internet users from Japan, Corea, China or Australia had to wait 300 milli seconds avaragely, this values were more than halved now. Most drastically this decrease shows effect in Japan where the times were cut from 270 to less than 5 milli seconds. Requests from the USA for DE domains are also answered faster now by the both new servers at the American east and west coast. The response times were reduced from about 170 to 70 milli seconds.

In Europe the coverage was very hight recently. But it has been further improved by some more name servers. With the additional name server in London as an example the response time for Great Britain was halved to about 25 milli seconds.

Background: Name server

Name servers ensure that an Internet site is reachable, because these have the assigns between domain and numeric IP address saved. The central name server for all DE domains is run by the DENIC eG located in Frankfurt. Copies of the information of this primary name server are stored at several secondary name servers in Frankfurt, Karlsruhe, Dortmund, Stuttgart, London, Vienna, Amsterdam, Stockholm, Tokio, Elmsford, NY und San Jose, CA. The worldwide distribution ensures that the information is everywhere in a short time available and even a server failure don't lead to reasonable delays.

In peak times there are 20.000 and more requests to be answered by each server. At all there are more then a hundred million requests daily.
