Hello all, We just released a RIPE Labs article giving an update on the RIPE NCC’s campaign to sponsor fifteen RIPE Atlas anchors: https://labs.ripe.net/Members/alun_davies/update-first-five-sponsored-ripe-… <https://labs.ripe.net/Members/alun_davies/update-first-five-sponsored-ripe-…> Best regards, Alun Davies RIPE NCC

Measuring SCTP and DCCP compatibility
by Felix Konstantin Maurer 22 Mar '17

22 Mar '17

Hi, I'm interested in measuring the support of new transport protocols in consumer routers. As IPv6 does not need rely on NAT anymore, most routers probably only have a firewall for IPv6 traffic. I assume that these firewalls drop traffic they do not understand, but I'm curious to see if it is actually true, or whether we have the possibility to use new transport protocols now. As far as I can see, there are only a limited number of possible measurements possible with Atlas probes. Do you think they could be extended to be more flexible and for example allow measurements using SCTP? Regards Felix

Cannot understand the daily limit
by Stephane Bortzmeyer 22 Mar '17

22 Mar '17

RIPE Atlas just denied me a measurement: "{"error":{"status":400,"code":104,"detail":"Executing this measurement request would violate your maximum daily spending limit of 1000000 credits. Please stop some of your currently running measurements and try again.","title":""}}" I have one permanent measurement, which takes, according to <https://atlas.ripe.net/user/credits/>, 3400 credits/hour (81600/day). Otherwise, I ran only one-off measurements, most taking < 1000 credits. How could I hit a limit of ONE MILLION per day?

Starting again a stopped custom measurement
by Sylvain Pascou 22 Mar '17

22 Mar '17

Hello, This might seem like a silly question but I've found no way, whether through the Web UI or the POST API, to start a measurement that I have previously accidentally stopped. Is this a problem or simply a not-implemented feature? Sylvain Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Trivia of the day: Atlas probes and alternative DNS roots
by Stephane Bortzmeyer 21 Mar '17

21 Mar '17

A quick test with a thousand probes seem to indicate that less than a dozen of all the probes use an alternative DNS root (or, more stricly, use a DNS resolver which is configured for an alternative root). The only alternative root used seems to be OpenNIC. Measurements #7865679 #7865870 #7865872 #7865873

Fwd: [mat-wg] Atlas: DNS TCP Errors
by John 14 Mar '17

14 Mar '17

Hello Atlas, 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…

Lowercase country codes in the probes database
by Marat Khalili 14 Mar '17

14 Mar '17

While using use probes database at ftp://ftp.ripe.net/ripe/atlas/probes/archive/ I noticed that 33 probes have country_code values in lower case (e.g. "ru" instead of "RU"), some in "Connected" state. When trying to distribute probes evenly among available countries it obviously affects the result. Of course, it's easy to work around once you are aware of this 'feature', but I only found the problem by chance. I wonder what's the story behind this and can this be fixed? (Web-interface doesn't seem to be affected.) -- With Best Regards, Marat Khalili

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

Surplus RIPE Atlas credits
by Michael Reutter 13 Mar '17

13 Mar '17

Hi everyone, I host a probe but at the moment I do not create measurements. As such, I have a large surplus of unused credits. Is anyone in need of credits and would like for me to transfer them? Best, Michael
