placing a probe into wireless networks (not terrestrial)
by Kurt Kayser 11 Nov '22

11 Nov '22

Dear Atlas-ml-followers, this a summary of a brief discussion I had with Michel Stam during RIPE85. We believe there might be a great value putting up a public Internet monitoring probe (vantage point) into low earth orbit satellite systems, such as Starlink. Monitoring from terrestrial end-points delivers high variances, due to frequent sat-changes. If we could put up an ATLAS-probe (be it SW - which is probably easier than HW) into a specific plane, we could add interesting tests and try to interpret the values depending on position over specific areas, atmospheric influences, solar influences as well as other effects that would change signal patterns. I would be offering support to try to establish such a probe and help to setup a project defition. Any thoughts or feedback to this idea? Best regards Kurt Kayser

Credit sponsorship
by Finn Holler 07 Nov '22

07 Nov '22

Hello, I am looking for probe operators, with a credit surplus, who would want to transfer some credits to my RIPE Atlas account (email: finn.holler(a)student.uni-tuebingen.de). These credits are required for me to interact with the measurement API, which I want to explore and ideally use, to implement a service indicating the connectivity status of various internet services to tenants of local student housing. The plan is to register some probes, so this credit sponsorship is only necessary for initial trials. Best, -Finn

Breaking API change?
by Ray Bellis 26 Oct '22

26 Oct '22

ISC's Root System Atlas visualiser used to use this API call to access the built-in root system measurements: <${apiUrl}/measurements/${m}/latest/?fields=responses.0.response_time,responses.0.abuf.answers.0.data.0&freshness=1800> where ${m} is the measurement number. It used to return this object: { probe_id1: [ [ latency, site1 ], ... ] probe_id2: [ [ latency, site1 ], ... ] ... } It now returns this array instead: [ [probe_id1, latency, site], ... [probe_id1, latency, site], [probe_id2, latency, site], ... ] and I had to explicitly request the probe_id field in order to get it. Was this change intentional, a regression, or did I not use the API right in the first place? cheers, Ray

V4 probe looses connection
by Szabolcs Sipos 22 Oct '22

22 Oct '22

Hi, I have a probe (#53985, V4, fw: 5070) that goes offline after 1-2 days of uptime and does not recover unless rebooted. The probe responds to ping (even from a different subnet). Packet capture reveals that it renews its DHCP lease normally, but does not initiate any higher level connection. I will try to keep the probe online for a few days so that you can run some tests if you wish. Regards, Szabolcs

Shared probes not shown anymore in "my atlas"
by Dave 20 Oct '22

20 Oct '22

Hi, In the past the probes that had shared management were shown below the owned probes. This is not the case anymore. Is this intentional? Can it be restored? Thanks, Dave

ATLAS page broken because of Cloudflare
by Max Grobecker 16 Oct '22

16 Oct '22

Hi, on my network, the RIPE ATLAS page is not working because mandatory resources (i.e. Javascript) can't be loaded, because appearently ripe.net is now running behind Cloudflare and is blocking requests to static resources - see attached network console screenshot of my browser. There should be made a rule to exclude static assets or trusted origins from this type of filtering. This is maybe also affecting other pages, which include resources directly from www.ripe.net. I'm accessing this over a mobile network via IPv6 (Telefonica Germany), so it's not a "other bad person behind same CGNAT" problem but a seemingly static rule to always challenge the client. Greetings, Max

Tagging probes which are using the ISP's DNS server?
by Max Grobecker 11 Oct '22

11 Oct '22

Hi, a few days ago I wanted to debug a name resolution problem of one of our domains. For this reason, I wanted to test if probes inside a specific ASN are having difficulties to resolve a specific name (because only customers of this ISP were complaining). This lead to very mixed results, mostly because some of the selected probes did queries to a public DNS service like Google, Quad9 and so on. The problem existed only with the provider's DNS servers for some reason. It did take some time to make a script which tried to filter out these probes, so I wondered if anyone else had the same use-case and problem. Is there a way to automatically tag probes, which are (seemingly) using the ISP's own DNS servers, or, at least, not a well-known public service? This could be done maybe by querying a special DNS name which returns the IP address from where the query was received (like "whoami.akamai.net"). By comparing the ASN of the probe and the ASN of the IP address returned by the DNS query, one could determine, if the ISP's servers are used. This would also be true for people running their own recursor, but this could be filtered as well very easy. If an ISP is using multiple ASN, this could be a problem. Maybe there's an easy solution for this as well. Probes which pass this test, could then be tagged with "DNS-using-ISP-server" or something like that and explicitly be selected for specific DNS resolution tests. Greetings, Max
