RIPE 86 routing-wg co-chair selection procedure
by Job Snijders 19 May '23

19 May '23

Hi all, At this point in time two candidates made themselves available to serve the community as Routing WG co-chair: Ben Cartwright-Cox and Alessandro Improta. I appreciate both candidates stepping forward. The following procedure will be used to select one candidate: step 1) The candidates are given 3 minutes of microphone time to introduce themselves to the working group and motivate their candidacy. step 2) After all statements have been heard, the working group is asked as many times as there are candidates to express support for the candidate through "IETF humming", or abstain through silence. step 3) The Routing WG co-chairs and RIPE community chairs delibrate together on their interpretation of the sound of the humming. step 4) If the humming appeared preferential to one of the candidates, the new co-chair has been found (procedure ends). If the humming could not be interpreted in a conclusive way, proceed to step 5. step 5) toss of a coin to overcome the tie-breaker (random selection) The procedure's objective is to gauge whether the working group has a clear preference for one or the other candidate, and if all candidates appear to be supported by the working group to make an arbitrary choice. The above procedure was agreed upon by Routing WG chairs & RIPE chairs. Execution of this process at the upcoming RIPE86 Routing WG meeting will serve as input into improving the description of the Routing WG chair selection document. Kind regards, Job outgoing co-chair Routing WG

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
