Dear colleagues, Last week, on Wednesday 4 May 2022, 14:00 UTC, we held a RIPE NCC Open House on the topic of RPKI Data. You can find the recording here: https://www.ripe.net/participate/meetings/open-house/ripe-ncc-open-house-rp… <https://www.ripe.net/participate/meetings/open-house/ripe-ncc-open-house-rp…> Thank you to all who participated, I thought it was a useful session and I enjoyed the discussion and feedback we received. During the session I promised to send an e-mail to this list with a summary of all data and visualisations we currently have public for RPKI: Visualisations: https://certification-stats.ripe.net/ <https://certification-stats.ripe.net/> -Generated from the RIR Trust Anchor Statistics https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> https://lirportal.ripe.net/certification/content/static/statistics/world-ro… <https://lirportal.ripe.net/certification/content/static/statistics/world-ro…> -Generated from "delegated stats” in combination with BGP data from RIS -No IPv6 Data: https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> -Documented on https://github.com/RIPE-NCC/internet-dataset-descriptions/blob/main/rpki-re… <https://github.com/RIPE-NCC/internet-dataset-descriptions/blob/main/rpki-re…> -Daily data per Trust Anchor per 2011 Public tools: https://rpki-validator.ripe.net/ui/ <https://rpki-validator.ripe.net/ui/> -User interface for Relying Party software https://stat.ripe.net/widget/rpki-by-trust-anchor <https://stat.ripe.net/widget/rpki-by-trust-anchor> -Generated from https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> https://stat.ripe.net/app/use-cases/asn/rpki-check/S1_3333_C16e <https://stat.ripe.net/app/use-cases/asn/rpki-check/S1_3333_C16e> (example) -Shows the RPKI validity state for a combination of prefix and Autonomous System. -Generated from https://rpki-validator.ripe.net/ui/ <https://rpki-validator.ripe.net/ui/> https://stat.ripe.net/docs/02.data-api/rpki-history.html <https://stat.ripe.net/docs/02.data-api/rpki-history.html> -API call returns a timeseries with the count of VRPs (Validated ROA Payload) for the requested resource. -Generated from https://ftp.ripe.net/rpki/ <https://ftp.ripe.net/rpki/> My key take aways from the session: -Ruediger Volk asked for an inventory of our current data, visualisations and tools. I started by this e-mail to the Working Group and I’m still considering how to make them easier to find on our website. -Randy Bush noted that experiments will/might pollute our data. Ties suggested to add known experiments to the GitHub dataset description. -Mingwei Zhang mentioned that he is currently working with Emile Aben and Agustin Formoso on “when did a VRP appear/disappear” feature for RIPEstat. This will be a very valuable addition for trouble shooting. -John Kristoff would like to see statistics on the time it takes from the moment someone hits “submit” in the LIR portal for a ROA, to the moment the VRP is visible in the repository and when it is seen picked up by routers. -Job Snijders mentioned that it would be beneficial to have ftp.ripe.net/rpki <http://ftp.ripe.net/rpki> data available as rsync://ftp.ripe.net/rpki <rsync://ftp.ripe.net/rpki> -Amreesh Phokeer suggested a more granular data set for Trust Anchor data. This is currently a daily dump. We are interested to hear how granular would be useful. Also Amreesh would be interested in statistics about revoked ROAs. -Ruediger Volk added that he would be interested in data that shows how frequent CRLs are used. Job Snijders provided insight in his mail to the WG: https://www.ripe.net/ripe/mail/archives/routing-wg/2022-May/004566.html <https://www.ripe.net/ripe/mail/archives/routing-wg/2022-May/004566.html> -Sacha mentioned that it would be useful to have a tool that would show how a ROA would impact a route, without actually creating that ROA, or for a prefix that you don’t have holdership of. -Nathalie said that she would like to get rid of the world map, as it is now well-known and does not include IPv6. A better alternative, that includes IPv6 can be found on: https://rpki-maps.nlnetlabs.nl/ui/world.html <https://rpki-maps.nlnetlabs.nl/ui/world.html> We’re looking into all your suggestions and where possible implement them. Stay tuned :) If I missed something, or if you want to share your thoughts, have suggestions, please send an e-mail to the list or directly to us on rpki(a)ripe.net <mailto:rpki@ripe.net> Kind regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

follow-up on RPKI open house: are CRLs used?
by Job Snijders 04 May '22

04 May '22

Hi, A question was raised during today's RPKI Data Open House: "are CRLs used?" Just now I ran some statistics on today's RPKI state using the 5 RIR TALs: * There are 30,914 CRL files. * In totality, these 30K CRLs list revocations for 331,637 serials. * 5,369 CRL files don't list revoked serials (at this point in time). * On average, the non-empty CRLs list 12 revoked certs. Further analysis can be performed using this JSON representation of the global RPKI state: https://console.rpki-client.org/dump.json (174 megabyte) https://console.rpki-client.org/dump.json.gz (38 megabyte) The dump.json file is regenerated a few times a day. Kind regards, Job

HTTP 503 responses for rrdp.ripe.net for locations in the United States
by Ties de Kock 25 Apr '22

25 Apr '22

Dear colleagues, Today, between approximately 6:41 UTC and 10:31 UTC, 503 responses were served for rrdp.ripe.net from multiple CDN edge locations in the United States. When we received a report of this issue at 12:09 UTC, we mitigated potential issues by switching CDN providers before starting our investigation. The CDN in use at the time uses a cache between the origin and edge locations. We expect the issue to be limited to CDN edge locations in Atlanta and Dallas (usatl1-edge1, usatl1-edge2, usdal-edge1, and usdal-edge2). Due to this location, this issue was not visible to us from our monitoring locations in Europe. We monitor that the objects in the RRDP snapshot that each CDN provided caches are in sync with our CA system but do not monitor individual CDN edge locations. However, during an extended outage, relying party instances will fall back to rsync. We did not observe a significant increase in the rate of rsync connections during the outage period. No rsync connections were dropped because of rsync capacity, with a peak of 200 connections and the 15-minute average peaking at 68 connections. Based on this, we expect the impact to have been limited. We are still investigating the exact impact. Please share any information you have on this issue with us via rpki(a)ripe.net. Kind regards, Ties de Kock

New on RIPE Labs: Detecting DNS Root Manipulation
by Alun Davies 19 Apr '22

19 Apr '22

Dear colleagues, In 2021, when reports emerged that hosts in Mexico were unable to reach whatsapp.net, it was determined that middleboxes were to blame. These devices were intercepting the queries to the root instance hosted in China and sending a bogus reply. Taking this as their starting point, Qasim Lone and colleagues have been investigating the prevalence of middleboxes using RIPE Atlas: https://labs.ripe.net/author/qasim-lone/detecting-dns-root-manipulation/ Best regards, Alun Davies RIPE Labs Editor RIPE NCC
