Proposing Making RIPE Atlas Data More Public
Proposing Making RIPE Atlas Data More Public
Vesna Manojlovic — 17 Dec 2013

RIPE Atlas is now three years old, and is moving from a prototype to production service. Based on our experience so far, observing typical usage and listening to user feedback, we suggest opening up the publication of measurement data further. In this article we aim to clarify the current situation regarding privacy, and ask for community input about our suggested plan to move forward. … Read more

Typhoon Haiyan - What we see in RIPEstat and RIPE Atlas
Emile Aben — 08 Nov 2013

As one of the strongest typhoons on record, Haiyan is feared to have a devastating effect on the Philippines. We looked for evidence of its effects on the country's core Internet infrastructure. At first glance, the typhoon's impact on core Internet infrastructure appears to be modest. This is in stark contrast with the expected humanitarian situation in the affected area.… Read more

RIPE Atlas Terms and Conditions for Anchor Hosts
Vesna Manojlovic — 03 Oct 2013

RIPE Atlas anchors is transitioning from a pilot project to a production service. As such, we want to clarify the terms and conditions that describe the use of the service and spell out both the user's and the RIPE NCC's obligations. Here we present a draft of these documents and ask for feedback, as we want to ensure we keep the community involved in every step of the process.… Read more

RIPE Atlas - Packet Size Matters
RIPE Atlas - Packet Size Matters
Emile Aben — 02 Oct 2013

This new RIPE Labs article talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmented packets, while they don't encounter problems with smaller unfragmented packets. … Read more

The Seismograph And Other New RIPE Atlas Features
The Seismograph And Other New RIPE Atlas Features
Vesna Manojlovic — 05 Sep 2013

While developing RIPE Atlas, we are engaging with the community to get feedback on the features we are working on, and to help us with distributing the probes. This article highlights Seismograph, zoomable ping graphs, and other new features we have made available for RIPE Atlas users over the last two months. We also announce where you can meet RIPE Atlas developers and "ambassadors" in the following months. … Read more

Improved Routing Information Available via RIPEstat
Improved Routing Information Available via RIPEstat
Fatemah Mafi — 23 Aug 2013

Our Routing Information Service (RIS) has been collecting global BGP routing information for 12 years. During this period, many different interfaces to analyse and visualise accumulated data have been developed. In line with our long-term goals to provide more consolidated services, we will be integrating the RIS interface’s tools and services into RIPEstat.… Read more

Future of RIPE NCC Technical Services
Kaveh Ranjbar — 20 Aug 2013

As the new Chief Information Officer at the RIPE NCC, I’d like to take this opportunity to share with you some of my ideas about the future direction of the technical services we offer to the community. This includes focusing on RIPE Atlas as the RIPE NCC’s data collection system, RIPEstat as the RIPE NCC’s consolidated point for data retrieval, service agreements and other plans for hosted services like K-root, authoritative DNS servers and RIS data collectors, and a greater focus on data analysis. … Read more

All IP Addresses Are Equal? "dot-zero" Addresses Are Less Equal
Stéphane Bortzmeyer — 03 Jul 2013

In theory, all IP addresses are the same, and you can allocate them at random without a problem. 192.168.1.2 is certainly not better or worse than 192.168.1.15, right? But, in practice, certain IP addresses are regarded as "special" by some implementations and do not yield the same user experience. This is the case for the "dot-zero", IPv4 addresses in which the last byte is zero.… Read more

Using RIPE Atlas User Defined Measurements to Find the Most Popular Instances of a DNS Anycast Name Server
Stéphane Bortzmeyer — 03 May 2013

A DNS anycast name server has several physical instances, all behind the same IP address. Which one is used by a RIPE Atlas probe depends on the location of the probe in the BGP space. RIPE Atlas can query the physical identity of the probe and therefore help to determine which instances have the largest user base.… Read more
