Why did I get "Over the limit on number of results"?
by Eduardo Duarte 25 Oct '17

25 Oct '17

Hello, I schedule some measurements to run during today but I got an error on some of them. The error is "Over the limit on number of results". I have enough credits to run all the measures so I don't understand this message.

New on RIPE Labs: RIPE Atlas Probes as IoT Devices
by Mirjam Kuehne 20 Oct '17

20 Oct '17

Dear colleagues, As a follow-up to the presentation Robert Kisteleki gave during the IoT Roundtable Meeting in September [1], we have published a RIPE Labs article describing RIPE Atlas probes as IoT devices and some initial design decisions that we thought were important for such an infrastructure: https://labs.ripe.net/Members/kistel/ripe-atlas-probes-as-iot-devices Kind regards, Mirjam Kuhne RIPE NCC [1] https://www.ripe.net/participate/meetings/roundtable/september-2017/ripe-io…

status is confusing
by Dave 18 Oct '17

18 Oct '17

Hi, The status page of one of my probes says: I’ve been bitten a few times by misinterpreting this. Could these 2 things be put on separate lines? This does suggest the probe is up but only when you missed the red colour and didn’t get the meaning of the icon. Also, when you read the mail it may be hours later than when it was sent. So keep in mind that a receiver’s probe could be back online in the meantime. Often a mail will be checked on the mobile. The status on a small screen must be clear too. I’ll restart the probe and modem and it will work again but I would have done that on day 1 if the message was more clear. Thanks, Dave

New on RIPE Labs: Insights from RIPE Atlas Probe Disconnections
by Mirjam Kuehne 17 Oct '17

17 Oct '17

Dear colleagues, There are all kinds of reasons why RIPE Atlas probes might become disconnected. So, even though we'd like all probes to be connected all the time, disconnects can also tell us a useful story. Please find this new article by Emile Aben on RIPE Labs exploring what insights we can gain from RIPE Atlas probe disconnections: https://labs.ripe.net/Members/emileaben/insights-from-ripe-atlas-probe-disc… Kind regards, Mirjam Kuhne RIPE NCC

What is the meaning of 127.0.0.1 as probe resolver?
by Baptiste Jonglez 16 Oct '17

16 Oct '17

Hi, While looking at the result of built-in DNS measurements that use the probe resolvers, I noticed that a significant fraction of probes have "127.0.0.1" as a resolver. And the results are strange: performance is really bad, for instance measurement 30002 gives a median resolution time of 300 ms for these probes! What could be the meaning of this? It almost looks like a recursive resolver with no cache at all is running on the probes themselves. I was looking at this measurement: https://atlas.ripe.net/measurements/30002/ And here are some example probes that exhibit this "127.0.0.1" symptom: 6001, 6087, 6162, 6235, 6308. Any reasonable explanation is welcome! Thanks, Baptiste

Plan to Implement RIPE Atlas WiFi Measurements
by Robert Kisteleki 09 Oct '17

09 Oct '17

Dear colleagues, We wanted to update the community and let you know that we plan to start work on the proposed experiment with WiFi measurements in mid-2016. As we communicated in a recent RIPE Labs article, we will work with GÉANT as a test partner to learn more about the operational effects of introducing WiFi measurements to the RIPE Atlas system, in addition to the benefits we believe this could provide for the entire RIPE Atlas community. Please see the article for more details if you are interested: https://labs.ripe.net/Members/suzanne_taylor_muzzin/ripe-atlas-wifi-measure… We will continue to update you once we’ve begun work on this plan, and we welcome your comments in the meantime. Regards, Robert Kisteleki RIPE NCC

Probe disconnects
by RIPE 09 Oct '17

09 Oct '17

Hi, I have a probe ( #22583 ) at home connected via my DSL link, for IPv6 connectivity I use a Hurricane Electric ( tunnelbroker.net ) /48 tunnel. I noticed on the monthly report that my probe is showing lots of short ( 1-2 min) disconnects. But it only seems to happen when the connection address in the probe’s network tab is the IPv6 address. In that case the IPv4 Connection address is empty. If it’s showing the IPv4 the probe stays connected for days ( until the DSL link really disconnects). Is there a way to get the probe to ignore the IPv6 for connection status ? Or to mark it as disconnected when both iPv4 and IPv6 are disconnected ? Best regards, Paul van der Zwan

ipv6 ping to root name servers failing?
by Tapio Sokura 04 Oct '17

04 Oct '17

Hello, I noticed a few days ago from the built-in probe graphs that ipv6 pings started to fail to the a-root name server instance serving the probe I host. Now also the j-root serving the probe is dropping pings. Some other instances of the same root servers at the moment are still answering pings. If it is intentional that root name servers are starting to drop pings, something should probably be done to the built-in probe measurements/graphs. Does someone know more about this, will all roots be dropping pings in the future or is this just a Verisign thing (a and j operator)? Tapio
