Fifteen new RIPE Atlas anchors - including the first IPv4-only anchor
by Michela Galante 19 Sep '16

19 Sep '16

Dear colleagues, Fifteen new RIPE Atlas anchors have been activated since our last announcement in June, bringing the total number to 216: - us-abn-as54054, hosted by Deteque LLC in Ashburn, United States - us-sgu-as46309, hosted by Gartner Inc in Saint George, United States - lu-kay-as35733, hosted by EURid VZW in Kayl, Luxembourg - de-ham-as35258, hosted by akquinet Outsourcing in Hamburg, Germany - ua-iev-as24725, hosted by Hostmaster LLC in Kiev, Ukraine - ca-wnp-as18451, hosted by les.net in Winnipeg, Canada - de-dus-as12676, hosted by HKN GmbH in Düsseldorf, Germany - uk-lon-as34587, hosted by bet365 in London, United Kingdom - us-lax-as15133, hosted by Verizon Digital Media in Los Angeles, United States - us-lwc-as2495, hosted by KanREN Inc in Lawrence, United States - lb-bey-as12812, hosted by the American University of Beirut in Beirut, Lebanon (IPv4-only anchor) - pg-pom-as17828, hosted by Telikom PNG (sponsored by APNIC) in Port Moresby, Papua New Guinea - ch-zrh-as9092, hosted by Open Systems in Zurich, Switzerland - nl-ams-as34106, hosted by TMG/Telegraaf in Amsterdam, Netherlands - dk-hje-as39642, hosted by WNB ApS in Højer, Denmark You can find the full list of anchors, a map of their locations, a list of the hosting organisations and more information about RIPE Atlas anchors online: https://atlas.ripe.net/anchors/list/ As a follow-up to some discussion on this list, we wanted to reiterate that we made the decision to support IPv4-only anchors because the goal of RIPE Atlas is to measure as much of the Internet as possible, and right now, that includes IPv4-only networks. We also believe that measuring networks before and after they enable IPv6 provides useful data. IPv4-only anchors are clearly marked as such, and we will implement checks to ensure these anchors become IPv6-capable as soon as their ASNs begin announcing IPv6. In the meantime, the RIPE NCC will continue to actively promote IPv6 deployment through our training courses, IPv6 Act Now website, IPv6 Roadshows and other programs, and our IPv6 Program Manager will follow up with any hosts requesting an IPv4-only anchor to help them in any way possible. We believe that supporting IPv4-only anchors will provide a more comprehensive understanding of the Internet and that the entire Internet community will benefit from more measurement data. You can learn more in this RIPE Labs article: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ipv4-only-ripe-atlas-an… Interested in hosting a RIPE Atlas anchor? 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! Regards, Michela Galante RIPE NCC

"Invalid target" error for RFC 1918 space
by Yang Yu 18 Sep '16

18 Sep '16

Hi, I got "Invalid target" error when I tried to create a measurement to see how far some RFC 1918 prefixes got propagated (carrier not properly filtering customer announcement). What is considered invalid for each measurement type? Thanks. Yang

All my measurements now show Forbidden status. Is there a > way to increase the limit? yes, ask the team at atlas(a)ripe.net (cc-ed). the folks there can extend limits (not unlimited of course, these limits are there for a reason :) ), but would need some info from you: - what is the experiment you'd like to perform - what would you want the new limit to be (and why what you want to do can't be done with the current limits and/or existing measurements) - when does your experiment end (ie. when can we put the limits back to the default) - promise us that you'll acknowledge RIPE Atlas in a paper - send us a link/copy of the paper once it's published (i hope i'm not forgetting things :) ) cheers, emile

API probe search
by Hank Nussbacher 08 Sep '16

08 Sep '16

When searching for specific ASN probes via: https://atlas.ripe.net/probes/ and entering a search like "ASxxxx", why does the API ignore the letters AS and respond with probes that have an id of yxxxx or xxxxy or ASN yxxxy? Shouldn't it be if I specify a specific string of ASxxx the response should be *only *those probes in ASxxx or at the worst also ASxxxy? Thanks, Hank

Data delays on RIPE Atlas
by Romeo Zwart 08 Sep '16

08 Sep '16

Dear colleagues, We are performing some maintenance work on the backend clusters supporting RIPE Atlas. Unexpectedly, this is having an impact on the insertion speed of new data. This means that new data insertion is behind for a few hours. The maintenance work is expected to complete before the end of the day, at which point the backlog of data will be cleared up very quickly. We apologise for any inconvenience caused. Kind regards, Romeo

Changes in LatencyMon
by Marat Khalili 05 Sep '16

05 Sep '16

Dear list, LatencyMon <https://atlas.ripe.net/docs/tools-latencymon/> changed for me recently with only minimum latency value shown now instead of all three. I wonder if other people see this and what are the reasons behind the change? (Cannot say yet if changes are for better or worse, but I can find no announcement and so suspect that this can be unintentional.) -- With Best Regards, Marat Khalili

New on RIPE Labs: Another Look at RIPE Atlas Probe Lifetimes
by Mirjam Kuehne 26 Aug '16

26 Aug '16

Dear colleagues, We took another, more detailed look at probe lifetimes and the dynamics of probes connecting and disconnecting from the RIPE Atlas infrastructure to try to understand how to keep the network growing in the long term. https://labs.ripe.net/Members/wilhelm/another-look-at-ripe-atlas-probe-life… Kind regards, Mirjam Kuehne RIPE NCC
