I don't receive a one-time code when I'm trying to log in

Hi folks, When I'm trying to login, after entering my email address and password, I'm being asked to enter a one-time code. However, I don't receive any such email with a one-time code. I've tried multiple times, different browsers and also checked spam folder but it seems it's not sent. I managed to log in using the recovery codes (miraculously I didn't lose them :) ) but there seems to be a bug with send the one-time code. Best, Vasilis

Ask For Credit for Traceroute Measurements
by Semebia Wurah 06 Feb '25

06 Feb '25

Hello everyone, I hope this finds you well. My name is Semebia Wurah, and I am a Research Associate at Carnegie Mellon University Africa, working under the supervision of Prof. Theophilus Benson. We are conducting traceroute measurements using RIPE Atlas to analyze the Internet ecosystem in Africa, focusing on the growth of AS peering and IXP utilization. Our research aims to provide insights into the region’s interconnection landscape and help identify opportunities for improving local traffic exchange. We would greatly appreciate any credits you can share to continue our measurements. These credits will enable us to perform additional traceroutes and expand our analysis. Please let me know if you need any further information. Thank you in advance for your time and support!

Credits for an assignment
by Stuhrberg, Florian 03 Feb '25

03 Feb '25

Dear all, I hope you are doing well. My name is Florian Stuhrberg, and I am a master's student at Hasso-Plattner-Institut in Germany. As part of an assignment, I am currently investigating in DNS over UDP and DNS over TLS response times, using the RIPE Atlas and the corresponding API. However, after my measurements for DNS over UDP, I do not have sufficient credits to conduct the measurements for DNS over TLS. Is it possible that you could kindly share some RIPE Atlas credits, so that I can finish the assignment? Please feel free to let me know if you need any more information. Thank you in advance. Kind regards, Florian Stuhrberg

Why measurements using api are apt to fail while those using web interface can usually succeed?
by 孙乐童 02 Feb '25

02 Feb '25

Dear all, I have been attempting to use Atlas to launch traceroute measurements recently. Initially, I used ripe.atlas.cousteau to run the measurements in batches, keeping the total number under 10,000 to avoid exceeding the measurement limit. However, only 10% of the measurements returned successful results, while the other 90% showed the status "scheduling denied." Next, I tried launching only 12 measurements in batch, where each measurement contained one traceroute from a specific probe to a designated IPv4 destination. Out of these, 4 succeeded and the other 8 showed the status "specified". Following that, I launched the 12 measurements one by one with 2-second intervals, resulting in a success rate of 6 out of 12. However, when I increased the interval to 3 seconds, the success rate dropped to 4 out of 12. Interestingly, when I created the same measurements for the designated probes and destinations through the web interface, all of them were successful. Below is the Python code I used to launch the measurements: fromripe.atlas.cousteauimport ( Traceroute, AtlasSource, AtlasRequest, AtlasCreateRequest, AtlasResultsRequest, AtlasLatestRequest, ProbeRequest ) traceroute=Traceroute(af=4, target=dstip, description="traceroute subpref ip {} from {}{}".format(dstip, probe_type, probe_value), protocol='ICMP') if probe_type =='asn': probe_value =int(probe_value) source = AtlasSource(type=probe_type, value=probe_value, requested=1, tags={"include": ["system-ipv4-capable"]}) _key = ATLAS_API_KEY_2 for _ inrange(2): atlas_request = AtlasCreateRequest( start_time=datetime.utcnow() + timedelta(random.randint(0, 1)), key=_key, measurements=[traceroute], sources=[source], is_oneoff=True ) (is_success, response) = atlas_request.create() if is_success: print('create_task', dstip, is_success, response) msm_id = response['measurements'][0] return Could you kindly let me know if there might be an issue with my approach or provide any advice on how to improve this process? I would greatly appreciate any guidance. Thank you very much! Best regards, Sun Letong

Ripe Atlas Measurement Results and API Usage
by Huseyn Gambarov 30 Jan '25

30 Jan '25

Hello. I was implementing a mechanism to read the measurement results from the Ripe Atlas for many asynchronous measurements. In this process, I have faced multiple questions regarding the internal mechanisms of Ripe Atlas, and I would be thankful if you could help me clarify them. First, in the Ripe Atlas, I sometimes get “-1” in the result indicating 100% packet loss and sometimes very long RTTs. Can you tell me please what is the condition when Ripe gives up on a target and marks it as "-1”? Second, I have implemented asynchronous reading using web sockets and faced a rate limit on several concurrent web socket connections. The error message said: 'There are too many connections from this IP address. Try making multiple subscriptions on the same connection.’ Can you tell me please, if there is a limit on the number of subscriptions on the same connection? To solve the issue in the second question, I implemented a polling mechanism that periodically checks if the measurement is finished. In order to not overload the API, I attempted to retrieve multiple measurement results in a single call using the following API endpoint: GET /api/v2/measurements/{pk}/latest/ The documentation of that API endpoint states: "Get the most recent results from one or more measurements”. However, I need help understanding how to specify multiple measurement IDs in this endpoint, because all options I tried failed with HTTP status code 405 (Method Not Allowed). Could you please show me the correct way of using this API endpoint? Thank you! With regards, Huseyn Gambarov

Atlas UI: Redesigned Probe Detail Pages in Beta
by Stephen Suess 29 Jan '25

29 Jan '25

Hello Atlas friends, We’re excited to announce the early beta release of our redesigned probe detail pages in the Atlas UI. Over the past few months, we’ve been rethinking the structure and usability of these pages, and we’re sharing this early version to gather your feedback as we continue to develop and refine the design and features. Here’s how they are organised: - Overview: Probe information, map, traffic chart, links to measurements, and well-known target stats. - Network: IPv4/IPv6 overview and history. - Results: Grouped time-series charts for well-known targets and built-in measurements. - Manage: Tools for Sharing, Notifications, Transfer, SSH Key management, and Write-off. This release is very much a work in progress, and you can expect further changes and improvements as we iterate on the design and features. You can try it out by enabling the beta toggle in your preferences (https://atlas.ripe.net/prefs) We’d love for you to explore the new design and share your thoughts—your feedback will be instrumental in shaping the final version. For the full release notes you can go here: https://atlas.ripe.net/docs/releases/website/2025-01-28.html Thanks for being part of the community, and we look forward to hearing from you. Kind regards, Stephen Atlas UI
