Probe does not request IPv4 address via DHCP
by Stanish Stanishev 11 Jul '17

11 Jul '17

Hello, My probe(ID 16372) has disconnected from the Atlas network and in the Status I see USB flash corrupted. I did the troubleshooting - power off the probe, remove the USB, power on the probe, waited 10 mins, plugged brand new 4G USB. Several times with no success, So I decided to do a traffic capture of the uplink port where the probe is connected to. According to the capture the probe does not send DHCP requests. It sends only IPv6 traffic - Multicast Listener reports and Neighbor solicitation. Hence not getting IP address. I did several restarts - no change. Anybody has seen this issue before ? Any hints how to deal with such issue ? Thanks Stanish Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum

Monthly probe report says it was down for the entire month
by James Andrewartha 03 Jul '17

03 Jul '17

Hi, I got my monthly probe report and oddly it says my probe was down for the entire month, rather than the 14d 6h 55m (47.63%) the website says. I've only just been able to reboot the probe (it didn't respond to ping at all), and it has come up with a new IP, but hasn't connected to the controller. Some things have updated with the new IP, eg p29530.probes.atlas.ripe.net but others like the local address are still showing the old IP. Should I try doing the recovery procedure? Thanks, James -------- Forwarded Message -------- Subject: Monthly probe report for CCGS Perth (#29530) Date: Sat, 1 Jul 2017 01:50:21 +0000 From: RIPE Atlas <no-reply(a)ripe.net> Reply-To: RIPE Atlas <no-reply(a)ripe.net> To: linuxadmin(a)ccgs.wa.edu.au Dear James Andrewartha, This is your monthly availability report for probe 29530 (CCGS Perth).

atlas feature suggestion
by Geert Jan de Groot 20 Jun '17

20 Jun '17

Hi, On the portal: > Notifications > Notify me at my registration address if this probe is down for more than 600 minutes. This doesn't seem to take into account that a probe may be dual-stacked (v4 and v6) and just one of these protocols may fail w/o the other one failing as well (this is a problem with my CPE, but I'm not touching that box until the temperature in the lab has dropped to sensible values) In any case, if v6 dies but v4 still works, the probe doesn't complain. Perhaps this should be flagged separately? How are we doing on testing silent v6-failures in general? Happy eyeballs make a lot of breakage invisible.. Geert Jan

Improvements to the RIPE Atlas measurement creation form
by Chris Amin 15 Jun '17

15 Jun '17

Dear all, We’ve made some changes to the interface for creating measurements on the RIPE Atlas website (https://atlas.ripe.net/measurements/form/) that will make it both faster and more responsive. Users should also see similar improvements in the user interface for monitoring and configuring domains with DomainMON (https://atlas.ripe.net/domainmon/). The changes were made possible by switching to the public measurement API (https://atlas.ripe.net/docs/api/v2/manual/). Concurrently with this, we also improved the error reporting in the API to make it easier to find out the cause of errors. This API change is backwards compatible and is documented in the API manual (https://atlas.ripe.net/docs/api/v2/manual/overview/error_messages.html). Whilst we do not expect the transition to cause any issues, we kindly ask that users let us know if they experience anything out of the ordinary that might be related to the change. Best regards, Chris Amin RIPE NCC

Firmware Update for RIPE Atlas V1 and V2 Probes
by Alun Davies 09 Jun '17

09 Jun '17

Dear all, We’re currently in the process of deploying a new firmware update for RIPE Atlas V1 and V2 probes. The update provides a fix for a bug that caused around 15% of RIPE Atlas V1 probes to disconnect. As of the time of writing, the update is at approximately 60% deployment. If you’ve been unable to reconnect your RIPE Atlas V1 probe, you can return it to the following address to be fixed. If you’d like the probe to be returned to you afterwards, please let us know. Alternatively, we’d encourage you to apply for a V3 probe. RIPE NCC P.O. Box 10096 1001EB Amsterdam The Netherlands We’d like to take this opportunity to thank all probe hosts for your ongoing efforts in supporting RIPE Atlas. Cheers, Alun Davies RIPE NCC

Anchors as target hosts for SLA
by Antonio Prado 06 Jun '17

06 Jun '17

hi, do you think could be a good idea to use Ripe Atlas Anchors as target hosts for measuring respect of SLA terms of an Internet transit? SLA example This Internet transit should meet the following criteria: average round trip delay (echo request, echo reply) toward $NEAREST_ATLAS_ANCHOR should be less than 100ms on a 10k packets stream of pings; packet loss equal or less than 0.02% pros, cons, recommendations? thank you -- antonio
