Changes to the rpki archives on ftp.ripe.net
by Ties de Kock 26 Jan '24

26 Jan '24

Dear colleagues, As you may know, the RIPE NCC publishes daily RPKI dumps for all trust anchors on ftp.ripe.net/rpki. Today, we have made some changes to this longitudinal dataset. We have added: * The compressed JSON output of a validator (output.json.xz). We added this because it contains validated ASPA and BGPsec payloads. * A compressed version of the CSV file of ROAs (roas.csv.xz) * A xz compressed archive of the validated and unvalidated objects (repo.tar.xz) We made this change because it significantly reduces the size of the files. At this point, we do not plan to re-compress historic files. However, to realise the savings, we must stop producing the larger version at some point and clean up the "duplicate" files from the transition period. For now, we will create the old (roas.csv, repo.tar.gz) and new (roas.csv.xz, repo.tar.xz) side by side during a transition period. We plan to stop creating the old format after a transition period of at least a month, taking into account the feedback we receive. We will inform you when this happens. Ties de Kock Specialist Software Engineer RIPE NCC

PEARG: Guidelines for Performing Safe Measurement on the Internet
by Stephen Strowes 16 Nov '23

16 Nov '23

Hi, There is an open request on the IRTF's PEARG list, seeking feedback on a draft document, "Guidelines for Performing Safe Measurement on the Internet". The MAT WG has expertise and probably feedback to share. The request with appropriate pointers is here: https://mailarchive.ietf.org/arch/msg/pearg/-qGRRbBAZ2YAytwt4lpxVcQ7OZE/ Feedback on the draft is welcome either on their RG discuss list, or by filing issues directly against the git repo. Cheers, S.

Unauthenticated user access to RIPE Atlas
by Ben Cartwright-Cox 03 Nov '23

03 Nov '23

Hello everybody! I was wondering around what are the rules and views on “open user access” to RIPE Atlas ( as in non-authenticated users being able to make RIPE atlas measurements) I ask because as of this morning I noticed that hurricane electric’s bgp.he.net tool is now allowing users to make right atlas measurements without any authentication to RIPE Atlas, this was surprising to me as when I asked a NCC staff member at the last meeting in Berlin about doing something similar to this I was explicitly told that this would not be desired. I cannot remember who told me this ( and I don't have an easy way of finding out again ) but assuming this is allowed I will happily copy this for bgp.tools But I'd like to check with Atlas people before doing such a thing.
