Delays over the weekend
by Robert Kisteleki 29 Oct '18

29 Oct '18

Dear all, Some of you have noticed that there were delays in how RIPE Atlas behaved, starting on Saturday. This happened because of an issue deep in the bowels of the infrastructure which caused tasks (including measurement requests) to pile up. We believe the issue has been resolved by now, though we're still investigating the root cause of the issue. We apologise for the inconvenience this caused. Regards, Robert Kisteleki RIPE Atlas team

New set - wizard improvements suggestion
by Evgeniy S. 24 Oct '18

24 Oct '18

Dear All, finally we are using our ripe probes to monitor our resources from mobile networks. I found that current "new set - wizard" functionality is lacking some useful extra filters using: 1) "User tags" - then I can tag my mobile probes and select only mobile network probes from the list. 2) mine, favorites, sponsored, ambassadorships It will be also nice to request to tag mobile network probes for users who run them. Any feedback is appreciated. I'm also interesting for getting in touch with people who have probes installed in mobile networks to make tests / comparing to our setup. -- With regards, Eugene

Relocating a probe
by Gary Gapinski 20 Oct '18

20 Oct '18

Hello: I currently host a probe (#14102) at my residence. I will soon move to a new residence about 450 miles from the current location. Such a move will necessarily alter measurements obtained relative to past ones (as well as ASN, geolocation, etc.). Should the existing probe identity be retired in favor of a new identity? (And if so how might that be accomplished?) Regards, Gary

Definition of Commercial Use
by Mic Szillat 04 Oct '18

04 Oct '18

Hi folks, I have a discussion in my company about the definition of commercial use. Can we please get an official confirmation whether our typical usage of Atlas is covered by the terms of service? We occasionally use Atlas to debug network connectivity between our systems and those of our customers. We answer support requests and confirm or deny network issues based on the data collected. We do not give customers access to the measurement interface. Thanks, Mic

Extended CHAOS queries
by Moritz Muller 24 Sep '18

24 Sep '18

Hi all, I was wondering if it would be possible to extend the supported CHAOS TXT query arguments to trustanchor.unbound. and trustanchor.server? This would enable RIPE Atlas probes to measure which DNSSEC Trust Anchors Unbound and PowerDNS resolvers have configured (if they support this query). Cheers, Moritz

Is there a max running measurement number for a user
by Yihao Jia 30 Aug '18

30 Aug '18

Dear all, Is there a max running measurement number for a user? I try to launch about 800 measurements, but only about 150 of them succeed and keep running, while another 650 fail with the description "overlimited denied" one of the fail measurement is: https://atlas.ripe.net/measurements/15302198/ Do you know what's the reason I failed? (btw, I am wondering how to check the reason why a measurement is failed by the measurement id?) Many thanks, Yihao

The three generations of the Atlas probes : technical details
by BELLAFKIH hayat 30 Aug '18

30 Aug '18

Hi, I hope validate some details about the Atlas probes. I try to get these details by consulting the resources: 1. https://atlas.ripe.net/docs/probe-v1/ 2. https://atlas.ripe.net/docs/probe-v2/ 3. https://atlas.ripe.net/docs/probe-v3/ But no technical details given. By reading some presentations, I create the table bellow. Now, I hope if you can validate these details and complete the information about the CPU. It will be good if you can add the technical details for each generation of the probes. Thanks in advance. *Hayat BELLAFKIH*

Getting More Traffic for Probe
by Eren Türkay 27 Aug '18

27 Aug '18

Hello, I am running a probe [0] at my home and I have 240Mbit connection from my provider. When I look at the graphs, this probe is basically sitting idle doing nothing! I can spare 20Mbit/s easily for measurements to keep the usage. However, I do not know how to achieve that. Is it possible to attract more traffic to my probe? I'm sure there is some algorithm involved to distribute the work so if you can please get me some more work, I'd be pleased [obviously more credits to spare :)] [0] https://atlas.ripe.net/probes/31252/ Regards, -- . 73!

Probe for mobile network
by Evgeniy Sudyr 25 Aug '18

25 Aug '18

We have developed mobile application and we are interesting for making measurements from our customer''s networks using ripe atlas probes. I found no probes from interesting ASN, that's why I'm looking for a way to host own probes (we do have already) and connect it to interesting MNO networks using some USB sticks or even mobile phones (to use as 3G / LTE modem). Obviously we want to make less points of failure in between RIPE probe and mobile modem. Any luck to get USB sticks working with RIPE probe without some router in between? -- With regards, Eugene Sudyr

Failled to get traceroute results from the id 5151
by BELLAFKIH hayat 16 Aug '18

16 Aug '18

Hi all, I am trying to get traceroute results for the measurements id 5151 ( https://atlas.ripe.net/measurements/5151/) by using python module : Python client for RIPE ATLAS API, for period october 2016. For many days ( eg : 19, 20) in this period, the operation is failled. I got Killed ! I found that the reason of having Killed when running a python script is related to the ressources limits. Any helps? *Hayat BELLAFKIH*

Probe limit per measurement
by Schomp, Kyle 08 Aug '18

08 Aug '18

Hi all, I'm trying to use Ripe Atlas for monitoring a production system. I've hit the 1k maximum probes per measurement limit, however. I realize I could just split up the task among multiple measurements to stay under the 1k probes max, but that seems sort of hack-ish and possibly less efficient for the platform. Is it possible to get the limits increased? Thanks! -kyle

Processing RIPE Atlas data as Big Data
by BELLAFKIH hayat 24 Jul '18

24 Jul '18

Dear RIPE Atlas users, I am studying the processing of the data collected by the probes as a Big Data problem. For instance, one hour of traceroute data count for 500 Mo (bzip2), so 7 Go of data in text format. Can you share with me how you deal with these data in practice. are you using a super machine, Big Data tools? best regards, Hayat

Looking for advise and temporarily limits increment for research
by Yihao Jia 22 Jul '18

22 Jul '18

To whom it may help, My name is Yihao. I am a Ph.D. student. Recently I am doing a research with RIPE Atlas. However, my research requires many measurements in a short period, which breaks several rules of the Rate Limits. Since I really like and in hurry to use Atlas to support my research, is there any advice I can get from this? I'd like to describe why it would be necessary for my research. And if possible, may I get a temporarily limit increment for 10 days? Many thanks, Yihao Jia

"interval" is documented as "In normal (not one-off) measurements, this value represents the number of seconds between measurements by a single probe." I never tried "spread". I don't know the exact JSON you sent but this one worked (5 minutes, 1 minute between each test): {'definitions': [{'target': 'fr-ilm-as57119.anchors.atlas.ripe.net', 'af': 4, 'interval': 60, 'packets': 1, 'type': 'ping', 'description': 'Ping fr-ilm-as57119.anchors.atlas.ripe.net'}], 'start_time': 1532026200, 'stop_time': 1532026500, 'probes': [{'requested': 1, 'type': 'area', 'value': 'WW'}]} And it gave this measurement: https://atlas.ripe.net/measurements/15297080/

Global Traceroute
by Steve Gibbard 19 Jul '18

19 Jul '18

I wrote front-end to traceroute from the RIPE Atlas probes. It looks like a standard looking glass — you select a probe by location and AS number, enter a destination, and it does a traceroute. It’s on the web at https://www.globaltraceroute.com. If this looks useful, please check it out and tell me what you think. One of the things I've found frustrating when troubleshooting routing problems was the lack of information about inbound paths. Various measurement systems would tell me when performance was bad. Traceroutes from my own network would tell me what path traffic to a destination was taking outbound. Flow systems would tell me what interface inbound traffic was coming in on, and sometimes what peer it was coming through. But determining the full path inbound traffic was taking — why users of some ISP in Asia were having their traffic show up at one of my POPs in Europe, for instance, was much more difficult. I’ve been using looking glasses and commercial performance monitoring systems that allow traceroutes from their probes, but those often weren’t where the end users were. RIPE Atlas did have probes where a lot of my end users were, so I started configuring one time measurements on RIPE Atlas whenever I needed a traceroute from a simulated end user. But finding a suitable probe and configuring the measurement was too cumbersome to do when I wasn’t pretty desperate. This is my attempt to solve that problem. Thanks, Steve

For help: launching a periodical atlas measurement
by Yihao Jia 19 Jul '18

19 Jul '18

Dear all, I am so sorry for using a screenshot for my last email. And I'd like to redescribe the problem I have. I'd like to launch a periodic Ping measurement (with python). It starts at UTC-now to (for example) 5 minutes later. I'd like the probe do the Ping test in every 1 minute. Thus I can have 5 results in this measurement. I am a little confused because all example on documents is one-off. I guess error might happen around "is_oneoff", "interval", "spread". source code for this test is below and in the attachment. Could you help me in checking where I get wrong? Many thanks, Yihao ---------------------------------------------------------------------------------------------- from datetime import datetime, timedelta from ripe.atlas.cousteau import ( Ping, AtlasSource, AtlasCreateRequest ) ATLAS_API_KEY = "" source2 = AtlasSource( requested=1, type="probes", value="35704" ) ping = Ping( af=4, target="202.112.51.179", description="Test for periodic Ping test", packets=1, ) def request(): atlas_request = AtlasCreateRequest( start_time=datetime.utcnow(), stop_time=(datetime.utcnow() + timedelta(minutes=5)), key=ATLAS_API_KEY, measurements=[ping], sources=[source2], is_oneoff=False, interval=60, spread=60 ) (is_success, response) = atlas_request.create() return is_success, response if __name__ == '__main__': is_success, response = request()

Need help in launching a periodical atlas measurement
by Yihao Jia 19 Jul '18

19 Jul '18

Dear all, I am in trouble with launching a periodical Ping measurement. [image: image.png] my script is like this, but my measurement always fails. I tried several times with different modification on "interval" and "spread". [image: image.png] one failed example can be reviewed here: https://atlas.ripe.net/measurements/15282285/ It works well when I launch a one-off measurement, but every time I try to launch a periodic measurement with the setting above, it fails all the time. it probably because the "is_oneoff", "interval", "spread" is set wrong, but I can't find a good example for it. The idea of this test measurement is to start a Ping test every 1 minute, from UTC-now to 5 minutes later. Thus, I'd like to have 5-set result in this measurement. Could you help me check where I set wrong? Many thanks, Yihao

DNS measurement using the Probe's resolvers
by Rami Al-Dalky 18 Jul '18

18 Jul '18

Hi Everyone, I have a question about using the probe's list of resolvers when creating a DNS measurement. It is unclear to me whether the probe would send the query to all resolvers at the same time or not! Also, does the probe send the query to all resolvers in its list or to a subset of those resolvers? Is DNS eyeball implemented in the probes? Sincerely, Rami

Hi, We have an anchor at the company I work for that has been associated with the wrong RIPE Atlas account. We're trying to move it from that (personal) atlas account to a shared netops account, but can't find a way to do this. Is there a way to do this ourselves, or can someone from RIPE Atlas do it for us? Cheers, -- Clément 'wxcafé' Hertling
