Interesting Graphs - Nine Years of RIPE Database Objects
Robert Kisteleki — Sep 13, 2010 02:59 PM

Let's take a look at how the number of different RIPE DB objects changed in the last nine years. Many of the graphs are easy to understand, but some of them are not trivial.

Phase out of Reply-Size Tester
Wolfgang Nagele — Sep 07, 2010 10:00 AM

Back in December 2009 we released a tool with which you can test your DNS resolver for possible issues with a DNSSEC signed root zone. Now that the root zone has been signed in production since 15 July 2010 we will stop this service on Monday, 11 October 2010.

On 27 August 2010, the RIPE NCC's Routing Information Service (RIS) was involved in an experiment using optional attributes in the Border Gateway Protocol (BGP). As a result of this experiment, a small, but significant percentage of global Internet traffic was disrupted for a period of about 30 minutes. The following article provides some background information on the experiment itself and its effect on the network.
