New on RIPE Labs: TraceMON - Network Debugging Made Easy
by Mirjam Kuehne 10 Apr '17

10 Apr '17

Dear colleagues, TraceMON is a client-side tool for visualising network topology generated by traceroutes reaching one or more targets in a network. It provides a one-click access to a set of information useful during day to day operations. Please find more details on RIPE Labs: https://labs.ripe.net/Members/massimo_candela/tracemon-traceroute-visualisa… Kind regards, Mirjam Kuhne RIPE NCC

RIPE Atlas Infrastructure Maintenance (14 March)
by Paul de Weerd 13 Mar '17

13 Mar '17

Dear all, We'll carry out maintenance work on the core RIPE Atlas and RIPEstat infrastructure tomorrow (14 March 2017), approximately between 09:00 and 11:00 UTC+1. As a result, we will switch over to the reduced data set, limiting the amount of history available from the service. This affects RIPE Atlas, RIPEstat, RIS and DNSMON. We apologise for the inconvenience. Best regards, Paul de Weerd Senior Systems Engineer RIPE NCC

Atlas: DNS TCP Errors
by John 07 Mar '17

07 Mar '17

Hello Mat-wg, feature request, when preforming DNS queries over TCP would it be possible for the probe to differentiate between a timeout and a TCP Reset. Currently the result just records the following when it gets a reset[1]. `error.timeout: 5000` A similar feature to record ICMP prohibited for udp queries would also be useful but likely much harder. Thanks John [1]https://atlas.ripe.net/api/v2/measurements/7859749/results?start=14888448…

Dear colleagues, Thanks to nineteen new RIPE Atlas Anchors being activated over the last three months, we have now reached an important milestone: 250 anchors online! Congratulations to anchor 250 hosted by Mogul Service and Support LLC in Ulaanbaatar, Mongolia and to APNIC for sponsoring it! These are the other anchors that have become active since our last announcement in November: - nl-ede-as12859, hosted by BIT in Ede, Netherlands - de-tua-as21413, hosted by envia TEL GmbH in Taucha, Germany - de-ham-as12731, hosted by IPHH Internet Port Hamburg GmbH in Hamburg, Germany (replaces older hardware) - py-slo-as27733, hosted by IXpy (sponsored by LACNIC) in San Lorenzo, Paraguay - uk-did-as786, hosted by Jisc in Didcot, United Kingdom - Two anchors hosted by Rabobank: nl-bst-as8211 in Best and nl-bxt-as8211 in Boxtel, Netherlands - nz-wlg-as9834, hosted by Trade Me in Wellington, New Zealand - lt-vno-as21412, hosted by CGATES in Vilnius, Lithuania - de-ber-as25291, hosted by SysEleven GmbH in Berlin, Germany (replaces older hardware) - us-bcb-as1312, hosted by Virginia Tech Transportation Institute in Blacksburg, United States - Two anchors hosted by Elisa Obj: fi-hel-as6667 in Helsinki and fi-tmp-as719 in Tampere, Finland - lu-ezt-as2602, hosted by Fondation RESTENA in Esch-sur-Alzette, Luxembourg (replaces older hardware) - de-kae-as8560, hosted by 1&1 Internet SE in Karlsruhe, Germany - fr-par-as5377, hosted by Marlink Enterprise AS in Paris, France - fr-tls-as39405, hosted by FULLSAVE in Toulouse, France - nl-ams-as286, hosted by KPN Eurorings B.V. in Amsterdam, Netherlands - mm-rgn-as132167, hosted by Ooredoo Myanmar (sponsored by APNIC) in Yangon, Myanmar (IPv4-only anchor) - fr-ilm-as57119, hosted by NAITWAYS in Issy, France - us-lxa-as8560, hosted by 1&1 Internet Inc. in Lenexa, United States 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/ Interested in hosting a RIPE Atlas Anchor? Learn more: https://atlas.ripe.net/get-involved/become-an-anchor-host/ There are several organisations that want to host a RIPE Atlas Anchor but don’t have the necessary funding. Find out more about the RIPE NCC campaign to sponsor 15 RIPE Atlas Anchors https://labs.ripe.net/Members/alun_davies/campaign-to-sponsor-15-ripe-atlas… We would also like to remind you about our ongoing cooperation with APNIC, LACNIC, AFRINIC and ISOC: thanks to their help we are getting more geographical diversity to the measurement data. If your organisation is in their region contact us at <atlas(a)ripe.net> and we will get you in touch with them! And don’t forget to let us know by contacting us at <atlas(a)ripe.net> if you’re doing something interesting with RIPE Atlas data - we always want to hear about your use cases, research and experiences!

Querying popular domains with RIPE Atlas
by Chris Amin 21 Feb '17

21 Feb '17

Dear colleagues, As you are probably aware, DNSMON* and RIPE Atlas built-in** measurements are often used when analysing outages and other issues with important DNS services, particularly the root zone servers. These measurements do not provide a direct indication of the impact on actual end-user experience because they involve directly querying authoritative name servers, thereby ignoring the effects of having multiple authoritative name servers as well as caching local recursive resolvers. To improve upon our DNS monitoring, we will initiate two built-in DNS measurements from all RIPE Atlas probes that use the probes' default resolvers instead of authoritative name servers. The first measurement will query for random top-level domains with the intention of avoiding caches and therefore hitting at least one root name server. The second measurement will query for popular domain names, with the intention of hitting caches where appropriate and getting an idea of the true impact on users. As a starting point for the second measurement, we will use a recent snapshot of the global top 50 visited sites according to the Alexa top sites list***, which combines unique visitors and individual page views in its calculations. Probes will cycle through these domains, querying for a different A record every 10 minutes. Since DNS queries containing these domains will be made from every connected RIPE Atlas probe, we would like to ask for feedback on whether querying the DNS for any of these domains could pose legal or political problems for probe hosts in certain parts of the world. I have also included the next 25 most popular domains below, which will be used to fill any gaps caused by removing items from the main list.
