by Mirjam Kuehne 19 Jul '16

19 Jul '16

Dear colleagues, With the attempted coup in Turkey, reports went out about social media being throttled and/or blocked. We analysed data about this that we collected with RIPE Atlas and the Open Observatory of Network Interference (OONI). Please find the results on RIPE Labs: https://labs.ripe.net/Members/emileaben/internet-access-disruption-in-turke… Kind regards, Mirjam Kuehne RIPE NCC

Keep All RIPE Atlas Data Accessible in the Standard Way
by Daniel Karrenberg 25 May '16

25 May '16

At today's meeting the RIPE NCC raised the question whether RIPE Atlas Data could be "archived" and longer be accessible by the 'standard API'. I consider this a bad idea because we will loose the ability to access the data with current and future tools, both RIPE NCC tools and those developed by the community using the Atlas API. Long baselines are useful not only for scientific research, but also for developing robust tools and applied research. We have not heard why the RIPE NC has raised the question. So I propose that we ask the RIPE NCC to prepare a detailed proposal including the motivation for proposing this. Until that happens we should keep all RIPE Atlas Data accessible as usual and not spend any time discussing this. Daniel

Proposal: Discontinue Private Measurements in RIPE Atlas
by Daniel Karrenberg 25 May '16

25 May '16

Keeping measurements and results private in RIPE Atlas comes at a significant cost. Latest case in point is the streaming interface where the developers tell me a significant part of the effort was filtering out results from private measurements. This surprises me because iirc we already decided that results from private measurements were indeed public and only the measurement specifications and meta data would be private. Be that as it may I propose that we ask the RIPE NCC to make a plan to remove private measurements from RIPE Atlas altogether and present it well before the next meeting. We can then have a discussion, build consensus and maybe arrive at consensus about this at the next RIPE meeting. Daniel

v4 versus v6 -- who connects faster?
by Bajpai, Vaibhav 23 May '16

23 May '16

Hello, -- sorry for cross-posting Here [a] is a toy v6 service I came up with during the RIPE Atlas hackathon over this weekend. Thought I share this along: [a] http://goo.gl/hbzbwD You enter a dual-stacked website (ALEXA top 10K) and it shows you the difference in TCP connect times over v4 and v6 as seen by all dual-stacked RIPE Atlas probes (~1.3K probes). You can also filter the visualisation from a specific origin-AS. This additional filter can be useful to view performance towards a website from a specific origin-AS (say DTAG). Disclaimer: This is an outcome of a 1.5d long hackathon project. As such, the codebase is possibly inundated with bugs. Please don’t see it as a production service :-) Best, Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com Room 91, Research I School of Engineering and Sciences Jacobs University Bremen, Germany ===================================

New on RIPE Labs: There Is Gold in This Stream - Sifting Through Used RIPE Atlas Traceroute Results
by Mirjam Kuehne 20 May '16

20 May '16

Dear colleagues, Please find a new article on RIPE Labs demonstrating the value of the results collected by RIPE Atlas independent of the original purpose for collecting them. Using all traceroute results from a particular day as an example, we first show that near real-time analysis of the result stream is feasible. Then we show that this has great potential for studying the packet layer of the Internet in general and for providing tools to network operators in particular. All this suggests a large and diverse potential for further work. https://labs.ripe.net/Members/dfk/there-is-gold-in-this-stream?pk_campaign=… Kind regards, Mirjam Kuehne RIPE NCC

[dagstuhl seminar]: global measurements: practice and experience
by Bajpai, Vaibhav 12 May '16

12 May '16

Dear RIPE Atlas / MAT WG -- sorry for cross-posting. A SIGCOMM CCR article summarising the Dagstuhl seminar on ‘Global Measurements: Practice and Experience’ just came online [a]. Thought to share it with you: [a] http://www.sigcomm.org/sites/default/files/ccr/papers/2016/April/0000000-00… Background: ===================== We recently helped organise a Dagstuhl seminar on Global Measurements: Practice and Experience [b] from January 04 – 07, 2016. This was a followup of the seminar on Global Measurement Framework [c] which focused on the development of global Internet measurement platforms and associated metrics. [b] http://www.dagstuhl.de/16012 [c] http://www.dagstuhl.de/13472 The second seminar aimed at discussing the practical experience gained with building global measurement platforms. It brought together people who are actively involved in the design and maintenance of global measurement systems, who do research on the data delivered by global measurement systems, and who use data derived from global measurement systems in order to manage networks or services or as input for regulatory decisions. ===================== Best, Vaibhav =================================== Vaibhav Bajpai www.vaibhavbajpai.com Room 91, Research I School of Engineering and Sciences Jacobs University Bremen, Germany ===================================

New on RIPE Labs: How Elasticsearch and Kibana Help us Analyse RIPE Atlas Data Logs
by Mirjam Kuehne 29 Apr '16

29 Apr '16

Dear colleagues, RIPE Atlas backend applications run on more than 40 servers. Each day these machines can produce thousands of application logs of any kind of severity level. In order to be able to track down serious errors, warnings or even unusual behaviour, we decided some time ago to try Elasticsearch as a logging sink. In this article we will look at the design of such a system and describe how we can easily make sense from an ocean of logs: https://labs.ripe.net/Members/andreas_strikos/how-elasticsearch-and-kibana-… Kind regards, Mirjam Kuehne RIPE NCC

Last call for presentations and Draft programme for RIPE 72
by Benno Overeinder 02 Apr '16

02 Apr '16

Colleagues, A list of currently accepted RIPE 72 presentations is now published at: https://ripe72.ripe.net/programme/meeting-plan/draft-programme/ There are still few slots remaining for a final RIPE 72 programme and RIPE Programme Committee will accept new proposals until 15 April 2016. This is our last call for you to submit your proposals. You can find the CFP for RIPE 72 below, or at https://ripe72.ripe.net/submit-topic/cfp/, for your proposals for plenary session presentations, tutorials, workshops, BoFs (Birds of a Feather sessions) and lightning talks. Please also note that speakers do not receive any extra reduction or funding towards the meeting fee at the RIPE Meetings. Kind regards, Benno Overeinder RIPE PC Chair https://www.ripe.net/participate/meetings/ripe-meetings/pc -------------------->>><<<-------------------- Call for Presentations A RIPE Meeting is an open event where Internet Service Providers, network operators and other interested parties get together. Although the meeting is mostly technical, it is also a chance for people to meet and network with others in their field. RIPE 72 will take place from 23-27 May 2016 in Copenhagen, Denmark. The RIPE Programme Committee (PC) is now seeking content proposals from the RIPE community for the plenary sessions, BoFs (Birds of a Feather sessions), panels, workshops, tutorials and lightning talks at RIPE 72. See the full descriptions of the different presentation formats, https://ripe72.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 15 April 2016. Proposals submitted after this date will be considered depending on the remaining available space in the programme. The PC is looking for presentations covering topics of network engineering and operations, including but not limited to: - IPv6 deployment - Managing IPv4 scarcity in operations - Commercial transactions of IPv4 addresses - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange Submissions RIPE Meeting attendees are quite sensitive to keeping presentations non-commercial, and product marketing talks are strongly discouraged. Repeated audience feedback shows that the most successful talks focus on operational experience, research results, or case studies. For example, presenters wishing to describe a commercial solution should focus on the underlying technology and not attempt a product demonstration. Presenters should indicate how much time they will require. In general, the time allocated for the different presentation formats is as follows: - Plenary presentations: 20-25 minutes presentation with 5-10 minutes discussion - Tutorials: up to two hours (Monday morning) - Workshops: one hour (during evening sessions) to two hours (Monday morning) - BoFs: approximately one hour - Lightning talks: 10 minutes The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe72.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe72.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. The allocation of lightning talks will be announced on short notice---in some cases on the same day but often one day prior to the time slot allocated. - Presenters who propose a panel or BoF are encouraged to include speakers from several (perhaps even competing) companies and/or a neutral facilitator. - All presentation proposals will only be considered by the PC if they contain at least draft presentation slides (slides may be updated later on). For panels, proposals must contain a clear description, as well as the names of invited panellists, presenters and moderators. - Due to potential technical issues, presenters/panellists should be physically present at the RIPE Meeting. If you have any questions or requests concerning content submissions, please email pc [at] ripe [dot] net. -- Benno J. Overeinder NLnet Labs http://www.nlnetlabs.nl/

New on RIPE Labs: Support for Elliptic Curve Cryptography (ECC) in DNS Resolvers as Seen by RIPE Atlas
by Mirjam Kuehne 21 Mar '16

21 Mar '16

Dear colleagues, Please find this new article on RIPE Labs contributed by Maciej Andzinski: The Elliptic Curve Cryptography (ECC) is becoming increasingly popular in DNSSEC. While it is sometimes considered to be a remedy for the low DNSSEC adoption rate, there is also a lot of controversy around it. One of the main concerns is that DNSSEC-validating resolvers don't always make use of ECC. We used RIPE Atlas to measure the support for ECC in DNS resolvers. https://labs.ripe.net/Members/maciej_andzinski_2/support-for-elliptic-curve… Kind regards, Mirjam Kuehne RIPE NCC
