Identifying widespread outages using atlas?
by Rafal.Jankowski＠thomsonreuters.com 20 Jul '16

20 Jul '16

Hi I'm wondering if there is any good statistic tool that helps identyfing any widespread Internet outages using ripe atlas probes such as ISP issues (like todays http://www.bbc.co.uk/news/technology-36844712), cable cuts, etc. Normally I select probe and look into public measurements but it does not seem to be very effective. ________________________________ This e-mail is for the sole use of the intended recipient and contains information that may be privileged and/or confidential.

Stop time not retained when creating new measurement
by Bill Fenner 18 Jul '16

18 Jul '16

Hi, I created a new measurement this morning, https://atlas.ripe.net/measurements/4467029/ . Its status says: Timing 2016-07-16 07:35 No stop time defined but I filled in the stop time when I created the measurement via the web page; I saved the command that it gave me to invoke the API and it includes: ... "is_oneoff": false, "bill_to": "fenner(a)fenron.com", "stop_time": 1469361631 } a) this feels like a bug. Is it a bug? b) can I add the stop time post-facto, or should I remember to go back and click "stop"? Thanks, Bill

start one-off from probe overview page
by Job Snijders 15 Jul '16

15 Jul '16

Hi all, UI feature requests: It would be cool if there is a button to start a one-off measurement from a certain probe's overview pages. If I am at https://atlas.ripe.net/probes/25606/ - would be nice if I can immediately jump into a one-off, rather then copy-pasting the probe's ID and creating a new one-off UDM. Kind regards, Job

Error creating one-off ping measurement
by Jared Mauch 15 Jul '16

15 Jul '16

We are attempting to test some things and I’m getting this error. "A one-off measurement cannot have the interval field set” It seems to be a problem if this field is even blank, anyone else experience this? - Jared

Probe down
by Виталий Туровец 14 Jul '16

14 Jul '16

Hello there! I've got a probe #20190 (https://atlas.ripe.net/probes/20190/) and it shows disconnected status it Atlas Web UI. I've tried to reboot the probe, it gets the IP address from my router via DHCP and i can ping it, the probe opens TCP connection to 193.0.19.25:443 and that's it. The question: how do i make it connect to Atlas again? -- ~~~ WBR, Vitalii Turovets Software Engineer VITU-RIPE

Result streams not working
by Florencia Alvarez Etcheverry 13 Jul '16

13 Jul '16

Hello, I started working with RIPE Atlas last week, when I made a script to create a one-off ping measurement between two specific probes (which I ping to check if they were working). I used Cousteau API, by default I sent 3 packets and I had 5 seconds of timeout. I got the results one time and then it stopped working. I changed the timeout to 3 or 4 minutes and while waiting for the callback function to execute I checked on the webpage and I can see the results for every measure I launched. So I see the results on the page but they don't get to the stream and the callback function is never called. I also saw the status changed from "ongoing" to "stopped" several minutes after I've seen the results; which leads me to another question, when a measurement stops?, why if I already have the results of a ping (that is the only thing I've launched) it's still running? I tried with Cousteau and also directly with socketIO but it has the same behavior. When I took off the parameters "packets=1,interval=60" of the request (leaving default values), I got the result with Cousteau API, but not with the socket directly. When I run it again it didn't work, so it looks like it works one of 20 times. Is there something I could do or am I doing something wrong? Thank you, Florencia.

Troubleshooting USB stick issues - reaching out
by Vesna Manojlovic 11 Jul '16

11 Jul '16

Dear colleagues, recently, some of the third version of RIPE Atlas probes have had an issue with their USB sticks. We're still investigating what may be causing this issue, and in the meantime we have a possible solution, outlined in this RIPE Labs article (and below in the email) https://labs.ripe.net/Members/philip_homburg/troubleshooting-ripe-atlas-pro… These steps might not be a surprise to the users on this list, but on the 4th of July we reached out to almost 5000 hosts of "abandoned" probes, and we see immediate positive results! As you can see from some screenshots I quickly made, number of active probes have increased - from 8883 on 1st July, to 9323 this morning. Allowing for normal fluctuations, this is still a considerable increase -- and we are grateful! Thank you for all the effort that you put into keeping the RIPE Atlas network strong by keeping your probes connected. Kind regards, Vesna (and the RIPE Atlas team) === Steps to power-cycle probe without USB stick: 1. Unplug the probe from its power source 2. Remove the USB stick from the probe 3. Plug in the probe WITHOUT the USB stick 4. Wait for ten minutes 5. Insert the USB stick After an hour, check SOS-messages & "Status" tab Note: Only on a network with working DHCP. If you have configured probe to use static IP, this setting would be lost if trying the steps. If this didn't help, try using a new, brand-name USB stick that is at least 4GB in size (it does not need any preparation but its contents will be erased so make sure it does not store anything crucial) If the problem is still there, please contact us at atlas(a)ripe.net

sometimes no RTT?
by Antranig Vartanian 08 Jul '16

08 Jul '16

Hi all! I'm new to RIPE Atlas, and right now using it for educational purposes :)) lately I've seen that some of my traceroute measurements do not have RTT. although it's not completely ignored by the hop (I get the data like from, size, ttl), but only rtt is missing :)) any idea how, why and when does this happen? :) for a live example, check Measurement #4458653. 48th probe's 11th hop's 1st query (counting from zero, btw) does not have rtt :) thanks in advance! side question: is there an (un)official IRC channel? :) -- Antranig Vartanian | PGP Key ID : 0xDAB81456 https://antranigv.am | https://cert.am (* do one thing and do it well *)

development server?
by Ollivier Robert 06 Jul '16

06 Jul '16

Hello, I've been hosting a probe for quite sometimes and now that APIv2 is out, I've writing a Go library to access it. Is there a development server I could hit instead of the regular one in order to clutter the DB with temporary/trash measurements? Thanks. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto(a)keltia.net In memoriam to Ondine, our 2nd child: http://ondine.keltia.net/
