Probe DHCPv6 support
by Aleksi Pirttimaa 19 May '23

19 May '23

Hi! I recently received my v4 probe and I'm very happy with it. But unfortunately it doesn't support DHCPv6. I present a practical reason for implementing a DHCPv6 client on the probe. You see, my ISP doesn't send router advertisements with the prefix for stateless autoconfiguration set, and instead DHCPv6 must be used. I believe their decision could have something to do with the fact that the regulating body here requires ISP's to prevent IP address spoofing in consumer plans. And to meet that requirement my ISP may be using a feature similar to Cisco's IP source guard, where switch ports and/or mac addresses are passively associated to leased ip's or prefixes, breaking SLAAC. Unfortunately they hate letting consumers talk with their engineers so it's difficult to speculate this further. For now, I've put a stateful firewall appliance in front of the probe which provides SLAAC, it works just fine. Do you think a DHCPv6 client should be implemented?

Meta-information dumps for built-in measurements?
by Vasileios Giotsas 09 Nov '20

09 Nov '20

Is there any repository like https://ftp.ripe.net/ripe/atlas/measurements/ that contains meta-information about built-in RIPE Atlas measurements (the above repository contains meta-information only for public measurements)? I couldn't find anything similar in the new FTP repository at https://data-store.ripe.net/datasets/atlas-daily-dumps/ I guess using the API is an alternative but it would be more convenient to have such dumps Thanks, Vasileios

Planned Atlas downtime on 29 January
by Robert Kisteleki 06 Feb '20

06 Feb '20

Dear RIPE Atlas users, Please be aware that we plan to do maintenance work in the RIPE Atlas core infrastructure two weeks from now, on Wednesday 29 January, between 9:00-12:00 CET (Amsterdam time). The RIPE Atlas website, UI and API will be unavailable in this period. The probes should remain connected and results will be collected normally, although during this period they can only be accessed real-time via the streaming service. Apologies for the inconvenience this may cause. Regards, Robert Kisteleki

Using Atlas for Monitoring of Anycast DNS
by Klaus Darilion 20 Jan '20

20 Jan '20

Hello! I want to restart this old thread and ask for available tools. For our Anycast DNS cloud, I want to measure the "performance", ie the RTT from Atlas probes. 1. Create measurements (I can do that already ;-) 2. Analyze this measurements: - fetch measurement - analyze the probe locations (ie. country, continent) - create reports with average RTT from certain countries and continents This second step I have partly in old scripts using influxdb and grafana dashboard - but that was a proof of concept with bad code. So, before starting coding from the base - are there some available scripts which can do the second part? Is https://github.com/RIPE-NCC/ripe.atlas.sagan still the way to go for measurement processing or are there meanwhile some better/smarter libraries? ie something for php?

Probe is offline but shown online
by Andre Heinrichs 19 Jan '20

19 Jan '20

I’ve just discovered my probe #29384 blinking frantically while the website claims it had been online for more than a day (which can’t be true as my DSL had to get a new connection with a different IP). I tried rebooting the probe but all that got me is lower values of Power-Up time in the SOS requests the probe sends every couple of minutes. From what I can guess it looks like something in RIPE ATLAS isn’t working right. Would be great if someone could have a look. TIA, Andre, Who’s trying to get some sleep now.

Probe stability tags
by Chris Amin 08 Jan '20

08 Jan '20

Dear RIPE Atlas users, Due to an error in our backend systems, the probe stability tags ("system: IPv4 Stable 30d" etc) had been gradually becoming stale over the past three months, meaning that probes were not gaining or losing these tags when they should. This has now been fixed, so probes are once again tagged appropriately. We have improved our internal monitoring so this kind of issue will be noticed more quickly next time. Apologies for any inconvenience caused. Kind regards, Chris Amin RIPE NCC

New RIPE Atlas Terms&Conditions
by Robert Kisteleki 08 Jan '20

08 Jan '20

Dear RIPE Atlas users, We'd like to inform you that a new version of the RIPE Atlas Terms & Conditions has just been published. Most changes in this version are needed for the introduction of "software probes". The new version (3.4) is available at https://atlas.ripe.net/legal/terms-conditions/ and will be effective as of 11 February 2020. Regards, Robert Kisteleki

A new year's break for the probes
by Robert Kisteleki 03 Jan '20

03 Jan '20

Happy new year to all RIPE Atlas users! It seems we've given a little break to our probes so they can celebrate the new year too ... >From midnight 1 January until approximately noon 2 January there were no built-in measurements running. This is due to an overlooked fact where the built-in measurements had a pre-defined end date of 2020-01-01. The system dutifully observed this date and did not schedule these measurements any more. We fixed this setting on Thursday, 2 January and the system returned to normal operations shortly thereafter. As a consequence, there's a gap in the delivered measurement results for built-in measurements (i.e. IDs < 1 million). Results for the User-Defined Measurements were not affected. Please accept our apologies for the inconvenience this can cause. Regards, Robert Kisteleki
