The Internet in North Korea - Hanging by a Single Thread?
The Internet in North Korea - Hanging by a Single Thread?
Emile Aben — Aug 26, 2015 11:50 AM

North Korea is one of the most secluded countries in the world, but it is nonetheless connected to the Internet. We investigate North Korea's Internet connectivity in light of recent outages and discuss the fragile nature of its setup.

Is It Really Worth Peering at IXPs? A Comparative Study
Is It Really Worth Peering at IXPs? A Comparative Study
roberto di lallo — Aug 03, 2015 11:50 AM

We investigated the role IXPs play in the Italian Internet ecosystem. Do peerings at IXPs have a positive effect on key performance indicators such as latency, hop count, packet loss and jitter? Do they reduce the number of out-of-country ISPs traversed by traffic between users located in Italy and critical Internet services like banks and public administrations?

Analysing the K-root Anycast Infrastructure
Analysing the K-root Anycast Infrastructure
JH Kuipers — Jul 27, 2015 12:20 PM

Anycast is used by most of the DNS root-servers and other services like Cloudflare. It provides localisation and scaling benefits to clients using the anycasted service. An anycast service uses one IP for several instances of the same service. The routing system is then responsible for directing a client to the closest instance of the service. In theory, a client should always reach the closest instance, but it turns out that this is not always the case. At the DACS group of the University of Twente, we analysed the anycast infrastructure of K-root and tried to find how many clients reached the closest instance.

Extending RIPE Atlas' Reach

In an effort to increase the growth rate of connected RIPE Atlas probes and achieve better coverage across the globe, our Measurements Community Building team is experimenting with new outreach methods.

Delta-V Gets Take-off Speed
George Michaelson — Jul 16, 2015 02:41 PM

The adoption of the RPKI system is growing rapidly. To make sure the system scales, we’ve developed a new protocol that should drastically improve fetch times for RPKI repositories. This article explains how.

Despite the few RIPE Atlas probes available in Latin America, it is possible to obtain interesting measurements about changes in network architecture.

More Leaky Routes
More Leaky Routes
Geoff Huston — Jul 03, 2015 03:10 PM

Most of the time, mostly everywhere, most of the Internet appears to work just fine. Indeed, it seems to work just fine enough to the point that that when it goes wrong in a significant way then it seems to be fodder for headlines in the industry press.

Improving RIPE Atlas Coverage - Which Networks Are Missing?
Improving RIPE Atlas Coverage - Which Networks Are Missing?
Emile Aben — Jul 02, 2015 12:10 PM

In this article we compare RIPE Atlas deployment against user population estimates provided by APNIC to see which eyeball networks are missing out on RIPE Atlas probes.

Adventures in Using PGP for the RIPE Database
Adventures in Using PGP for the RIPE Database
Alex Band — Jun 23, 2015 09:20 AM

At RIPE 70, Tim Bruijnzeels presented some statistics on the type of authentication people use to update the RIPE Database. There was one data point that particularly stood out for me: 76% of all updates via email are done using an MD5 password. I was stunned, because this way you are required to send your password in clear text over the Internet...

Enabling Data Compression in RIPE Atlas
Enabling Data Compression in RIPE Atlas
Daniel Quinn — Jun 17, 2015 02:55 PM

We’d like to enable gzip compression on all of RIPE Atlas' measurement API calls — but thanks to the BREACH vulnerability, doing so could mean that some enterprising individual with an obscene amount of time on their hands might be able read the contents of the responses. This means measurement results as well as metadata for measurements — including the small number of measurements not marked as “public”. We believe the drawbacks are negligible, but we’re looking for community support.
