Late Revocation of CA Certificates due to Bug in RIPE NCC CA Software
by Ties de Kock 17 May '23

17 May '23

Dear colleagues, As a result of a software bug introduced in our RPKI CA system on 16 May at around 08:49 UTC, our CA system failed to revoke certificates for members/End Users that lost their final resources. This issue affected two certificates, one containing a /22 and another containing a single AS Number. In violation of our CPS [0, Section 4.9.5], we did not revoke the affected certificates within eight hours of changing the resources. These certificates did not issue any leftover CA products (ROAs). A fix for this issue was deployed to production today, 17 May at 08:20 UTC, and the two certificates were correctly revoked at 08:29 UTC on 17 May. Since the /22 certificate involved the consolidation of resources and no ROAs were present, we believe there was no impact on the validity of prefixes. Similarly, there was no impact for the AS Number returned to the free pool. We have checked the prefixes affected by all transfers that happened during the time period the bug was present. No other certificates were affected: Either the CA still had resources, or there was no CA certificate for the member/End User to lose resources. To detect bugs like this and to prevent them from being introduced in the future, we will (1) improve the monitoring that verifies that the resources of the published certificates match the registry and (2) introduce tests that cover this scenario. Kind regards, Ties de Kock Specialist Software Engineer RIPE NCC [0]: https://www.ripe.net/publications/docs/ripe-751

Dear Routing Working Group, As Job Snijders is going to step down as co-chair of the Routing WG we asked for volunteers, and I'm glad someone responded: Ben Cartwright-Cox. Chair selection is done during a RIPE Meeting (not on the mailing list), and we happen to have one next week in lovely Rotterdam: https://ripe86.ripe.net/programme/meeting-plan/ Our WG session will take place on Wednesday morning, 9AM CEsT. If you have questions about the chair selection process or want to volunteer please contact routing-wg-chairs(a)ripe.net, NOT this mailing list. Kind regards, Paul Hoogsteder co-chair of the RIPE Routing WG

Call for presentation Routing WG at RIPE86 (Rotterdam, Netherlands)
by Job Snijders 18 Apr '23

18 Apr '23

Dear RIPE Routing WG, This is a call for presentation proposals for RIPE 86! The RIPE 86 meeting takes place in about 66 days: https://ripe86.ripe.net/ We ask both the Working Group and RIPE NCC for presentation proposals for the eminent 1.5 hour Routing WG slot on Wednesday, May 24th, 2023. The Routing Working Group is concerned with all aspects of IP routing technologies. This includes dissemination and discussion of issues affecting operators, new technologies and new applications of current technologies, and discussion of concerns relevant to inter and intra-AS routing. A non-exhaustive list of topics of interest includes BGP, Routing Security, RPKI (ROV, ASPA, BGPsec), LSR (OSPF/ISIS), Anycast, and BGP Monitoring (MRT, BMP). When you submit a proposal please also include slides for the chairs to review. If you've presented similar material elsewhere please share with us when and where. Proposals can be sent to routing-wg-chairs(a)ripe.net We look forward to seeing you all in Rotterdam! Kind regards, Job, Ignas, Paul RIPE Routing Working Group Co-Chairs
