New on RIPE Labs: Reviewing the 2016 Leap Second
by Mirjam Kuehne 17 Jan '17

17 Jan '17

Dear colleagues, Last month we covered the 2015 leap second ahead of the insertion of a leap second at the very end of 2016. As stated previously, leap seconds can trigger poorly-tested code paths; leap second handling always unearths bugs and issues. This one was no exception! Please find more details on RIPE Labs: https://labs.ripe.net/Members/stephen_strowes/reviewing-the-2016-leap-second Kind regards, Mirjam Kuehne RIPE NCC

by Mirjam Kuehne 22 Dec '16

22 Dec '16

Dear colleagues, Four years have passed since the RIPE NCC announced its plans to put RIPE Atlas anchors into production. Since the first anchors went online in 2013, we’ve been working hard to both maintain and expand the network. As a result, we currently have 238 anchors deployed across 66 countries!

Dear colleagues, 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. Please read more on RIPE Labs in an article contributed by our new colleague Stephen Strowes: Preparing for the 2016 Leap Second https://labs.ripe.net/Members/stephen_strowes/preparing-for-the-2016-leap-s… Kind regards, Mirjam Kuehne RIPE NCC

RIPE Atlas Success Story: Zoom-in on Germany
by Vesna Manojlovic 12 Dec '16

12 Dec '16

Dear all, we wrote an article as an example of how cross-pollination between 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. We are still interested in expanding this platform in areas and networks that need more coverage. For pictures & links, go here: https://labs.ripe.net/Members/becha/ripe-atlas-success-story-zoom-in-on-ger… Text is bellow. Regards, Vesna In July 2016, during the IETF meeting in Berlin, the popular "RFC podcast" had a special episode aired an interview with Daniel Karrenberg talking about the RIPE NCC and RIPE Atlas. Thanks to the podcast listeners, and with the help of promotion on Twitter, the episode prompted many, many, MANY applications for new RIPE Atlas probe hosts. Because of both summer vacations and a temporary shortage of probes, there was a delay in shipping - but when the new batch of probes arrived at our office, we started shipping them to applicants, most of whom were from Germany. Currently, with regard to the number of active probes, Germany is leading with more than 1,000. This is more than the USA, which was in the lead for the previous few years. If you want to zoom in to this success-story, you can take a look at this RIPEstat widget. There you can see that, between 22 September and 7 October, the number of activated probes jumped from 999 to 1,157. Thank you to all the hosts, in Germany and elsewhere, who are helping to build RIPE Atlas - the largest active measurements platform! Actions Although we are happy that there is so much enthusiasm in Germany, we are still interested in increasing diversity of coverage. To this end, we're looking to reach out to: - Regions, countries and areas within countries with fewer probes - Networks (ASNs) with fewer probes - Deploying RIPE Atlas anchors instead If you would like to apply for your own RIPE Atlas probe, there is a special link just for the readers of this RIPE Labs article :) If you already have a probe, and want to get in touch: - Check out the Community pages - Follow us on Twitter - Be active on the mailing list

New on RIPE Labs: Reasons Dynamic Addresses Change
by Mirjam Kuehne 29 Nov '16

29 Nov '16

Dear colleagues, Please find this new article on RIPE Labs by Ramakrishna Padmanabhan: Reasons Dynamic Addresses Change Rama looked at why dynamic addresses change and found ISPs that renumber periodically, most commonly every 24 hours or a multiple of 24 hours. He also found that outages influence address changes. RIPE Atlas was used for the measurements. https://labs.ripe.net/Members/ramakrishna_padmanabhan/reasons-dynamic-addre… Kind regards, Mirjam Kuehne RIPE NCC

Learn more: https://atlas.ripe.net/get-involved/become-an-anchor-host/ We are particularly interested in deploying anchors in the Middle East, Western Asia, Latin America and Africa in order to add more geographical diversity to the measurement data. There are several organisations that want to host a RIPE Atlas anchor but don’t have the necessary funding. To learn more about sponsoring an anchor, or for any other questions, please contact us at atlas(a)ripe.net And don’t forget to let us know if you’re doing something interesting with RIPE Atlas data - we always want to hear about your use cases, research and experiences!
