The Next 42 RIPE Atlas Probes at Hackerspaces
The Next 42 RIPE Atlas Probes at Hackerspaces
Vesna Manojlovic — 28 Dec 2016

In this article, we give one example of the possible communities that are now easier to build around RIPE Atlas probes. With the tagging of similar probes, existing communities can use additional tools for creating and analysing RIPE Atlas measurements, such as "IXP Country Jedi", to create their own interpretation of the available data. We are hoping this is going to be an inspiration to the reader, and an invitation to play with the results and improve on the code. … Read more

Preparing for the 2016 Leap Second
Preparing for the 2016 Leap Second
Stephen Strowes — 15 Dec 2016

On 31 December this year, we're scheduled for another leap second. There are many stories about what leap seconds can do to infrastructure and applications, and rituals are built up around them. Such rituals stem from reality: leap seconds trigger poorly-tested code paths and run contrary to assumptions that system time always runs in one direction. It's useful to be aware of how your infrastructure handles leap seconds and how NTP servers handle them, so you can plan around the event. Here, we look at some of the NTP measurements the RIPE Atlas platform took around the last leap second, and approaches for handling them.… Read more

RIPE Atlas Success Story: Zoom-in on Germany
RIPE Atlas Success Story: Zoom-in on Germany
Vesna Manojlovic — 09 Dec 2016

Here is an example of how cross-pollination between two or more communities can create success. An overlap between IETF participants, RIPE Atlas users and listeners of a popular German podcast has led to growth in the deployment of RIPE Atlas probes (hardware devices that measure Internet infrastructure). We are still interested in expanding this platform in areas and networks that need more coverage. … Read more

Ambassador, You Are Spoiling Us
Ambassador, You Are Spoiling Us
Vesna Manojlovic — 01 Dec 2016

At the RIPE NCC, we are grateful for the contribution RIPE Atlas ambassadors make to the success of the RIPE Atlas measurements platform. In this article, we focus on a handy RIPEstat tool that can be used to visualise the results of their efforts. The tool provides a historical view of country-specific growth of RIPE Atlas probe numbers and allows for comparisons of up to four countries in the same graph. … Read more

Routing Detours: Can We Avoid Nation-State Surveillance?
Routing Detours: Can We Avoid Nation-State Surveillance?
Annie Edmundson — 09 Nov 2016

An increasing number of countries are passing laws that facilitate the mass surveillance of their citizens. In response, governments and citizens are increasingly paying attention to the countries that their Internet traffic traverses. In some cases, countries are taking extreme steps, such as building new IXPs and encouraging local interconnection to keep local traffic local. We find that although many of these efforts are extensive, they are often futile, due to the inherent lack of hosting and route diversity for many popular sites. We investigate how the use of overlay network relays and the DNS open resolver infrastructure can prevent traffic from traversing certain jurisdictions.… Read more

Ethics of RIPE Atlas Measurements
Ethics of RIPE Atlas Measurements
Robert Kisteleki — 07 Nov 2016

This article is intended to make RIPE Atlas users aware of ethical issues that could arise when using RIPE Atlas. We do not intend to propose any new formal processes or procedures to address the relevant ethical issues, but we do want to encourage members of the RIPE Atlas community to consider the ethical impact of their behaviour when using RIPE Atlas. … Read more

What Can You Do with One Million RIPE Atlas Credits?
What Can You Do with One Million RIPE Atlas Credits?
Vesna Manojlovic — 12 Oct 2016

RIPE Atlas lets you make customised measurements from thousands of probes around the world. These measurements cost credits, which users usually earn by hosting or sponsoring RIPE Atlas probes - or you may have just been given a million RIPE Atlas credits as a member of one of the Regional Internet Registries. Find out how you can best spend your credits to check your services' connectivity and troubleshoot potential issues. … Read more
