RIPE 74 call for late submissions, LTs, and one tutorial and BoF
by Benno Overeinder 14 Apr '17

14 Apr '17

Dear colleagues, Brief version: The RIPE PC invites submissions for plenary, tutorial, BoF and Lightning Talks. Longer version: As distinct from previous RIPE meetings, the RIPE Programme Committee decided to keep two plenary slots open for so-called “late submission”. These plenary slots gives the community the opportunity to submit presentations that report on recent developments, issues, security incidents, etc., that are relevant to the RIPE audience. Independent from the realisation of late submissions, the PC has received a fair amount of high-quality submissions for the first deadline on March 12th. From these submissions, we have selected 14 presentations to complete the RIPE 74 plenary programme and no second CFP with a deadline in April was required. For the tutorials and BoFs we have one slot for each available: - Monday morning, 2 hour tutorial slot - evening, 1 hour BoF slot Also please consider to submit Lightning Talks for the Monday plenary. During the week of the RIPE meeting we will accept LTs for Tuesday and Friday. Please submit your plenary “late submission”, tutorial or BoF submission via the PC submission system, https://ripe74.ripe.net/submit-topic/submission-form/. The deadline for the submissions is *April 26th*. Kind regards, Benno Overeinder RIPE PC Chair https://ripe74.ripe.net/programme/ripe-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 74 will take place from 8-12 May 2017 in Budapest, Hungary. 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 74. See the full descriptions of the different presentation formats, https://ripe74.ripe.net/submit-topic/presentation-formats/. Proposals for plenary sessions, BoFs, panels, workshops and tutorials must be submitted for full consideration no later than 26 April 2017. 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 - Data centre technologies - Network and DNS operations - Internet governance and regulatory practices - Network and routing security - Content delivery - Internet peering and mobile data exchange - Connected Things (aka. Internet of Things - IoT) 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 total for both presentation and any discussion The following general requirements apply: - Proposals must be submitted using the meeting submission system, https://ripe74.ripe.net/submit-topic/submission-form/. - Lightning talks should also be submitted using the meeting submission system (https://ripe74.ripe.net/submit-topic/submission-form/) and can be submitted any time up to and including the meeting week. Allocation of lightning talks will start a few days before the meeting, and will continue throughout the meeting. During the meeting, they may be announced on the day before the talk or even on the same day as the talk. - Lightning talks should also be submitted using the meeting submission system (https://ripe74.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/

Atlas: DNS TCP Errors
by John 07 Mar '17

07 Mar '17

Hello Mat-wg, feature request, when preforming DNS queries over TCP would it be possible for the probe to differentiate between a timeout and a TCP Reset. Currently the result just records the following when it gets a reset[1]. `error.timeout: 5000` A similar feature to record ICMP prohibited for udp queries would also be useful but likely much harder. Thanks John [1]https://atlas.ripe.net/api/v2/measurements/7859749/results?start=14888448…

Querying popular domains with RIPE Atlas
by Chris Amin 21 Feb '17

21 Feb '17

Dear colleagues, As you are probably aware, DNSMON* and RIPE Atlas built-in** measurements are often used when analysing outages and other issues with important DNS services, particularly the root zone servers. These measurements do not provide a direct indication of the impact on actual end-user experience because they involve directly querying authoritative name servers, thereby ignoring the effects of having multiple authoritative name servers as well as caching local recursive resolvers. To improve upon our DNS monitoring, we will initiate two built-in DNS measurements from all RIPE Atlas probes that use the probes' default resolvers instead of authoritative name servers. The first measurement will query for random top-level domains with the intention of avoiding caches and therefore hitting at least one root name server. The second measurement will query for popular domain names, with the intention of hitting caches where appropriate and getting an idea of the true impact on users. As a starting point for the second measurement, we will use a recent snapshot of the global top 50 visited sites according to the Alexa top sites list***, which combines unique visitors and individual page views in its calculations. Probes will cycle through these domains, querying for a different A record every 10 minutes. Since DNS queries containing these domains will be made from every connected RIPE Atlas probe, we would like to ask for feedback on whether querying the DNS for any of these domains could pose legal or political problems for probe hosts in certain parts of the world. I have also included the next 25 most popular domains below, which will be used to fill any gaps caused by removing items from the main list.

RIPE Atlas Success Story: Zoom-in on Germany
by Vesna Manojlovic 12 Dec '16

12 Dec '16

Dear all, we wrote an article as an example of how cross-pollination between communities can create success. An overlap between IETF participants, RIPE Atlas users and listeners of a popular German podcast has led to growth in the deployment of RIPE Atlas probes. We are still interested in expanding this platform in areas and networks that need more coverage. For pictures & links, go here: https://labs.ripe.net/Members/becha/ripe-atlas-success-story-zoom-in-on-ger… Text is bellow. Regards, Vesna In July 2016, during the IETF meeting in Berlin, the popular "RFC podcast" had a special episode aired an interview with Daniel Karrenberg talking about the RIPE NCC and RIPE Atlas. Thanks to the podcast listeners, and with the help of promotion on Twitter, the episode prompted many, many, MANY applications for new RIPE Atlas probe hosts. Because of both summer vacations and a temporary shortage of probes, there was a delay in shipping - but when the new batch of probes arrived at our office, we started shipping them to applicants, most of whom were from Germany. Currently, with regard to the number of active probes, Germany is leading with more than 1,000. This is more than the USA, which was in the lead for the previous few years. If you want to zoom in to this success-story, you can take a look at this RIPEstat widget. There you can see that, between 22 September and 7 October, the number of activated probes jumped from 999 to 1,157. Thank you to all the hosts, in Germany and elsewhere, who are helping to build RIPE Atlas - the largest active measurements platform! Actions Although we are happy that there is so much enthusiasm in Germany, we are still interested in increasing diversity of coverage. To this end, we're looking to reach out to: - Regions, countries and areas within countries with fewer probes - Networks (ASNs) with fewer probes - Deploying RIPE Atlas anchors instead If you would like to apply for your own RIPE Atlas probe, there is a special link just for the readers of this RIPE Labs article :) If you already have a probe, and want to get in touch: - Check out the Community pages - Follow us on Twitter - Be active on the mailing list
