iPlane traceroute Dataset
Harsha V. Madhyastha — Sep 23, 2010 07:50 PM

This dataset contains traceroutes from PlanetLab nodes and traceroute servers that are done as part of the iPlane project at the University of Washington. This data starts 2006-06-23 and is updated daily. The data hosted on the Data Repository is a copy of the original data that is hosted at the University of Washington, but the historical logs are remastered so they contain only a single tarball per day. Additional data gathered by iPlane such as link latency and loss measurements as well as processed versions of the traceroutes are available at

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.

DNS Clients Do Request DNSSEC Today
Daniel Karrenberg — Sep 06, 2010 11:05 AM

After the DNS root zone was finally signed and a number of TLDs began signing their zones, we were curious to see how many clients actually request DNSSEC information. First we looked at our server that provides secondary service to several ccTLDs.

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.
