Ending Support for the RIPE NCC RPKI Validator
by Nathalie Trenaman 15 Jun '21

15 Jun '21

Dear colleagues, This is a reminder that on Thursday, 1 July 2021, we will stop supporting the RIPE NCC RPKI Validator. This will have no impact on any of our core activities around the Resource Public Key Infrastructure (RPKI). After discussions we had with members and the wider community at this mailing list and at the last two RIPE Meetings, we agreed that this approach will allow us to focus on the core of RPKI and maintain a secure, stable and resilient RPKI Certificate Authority. We strongly recommend that any network operators still running our RPKI Validator switch to an alternative Relying Party software [1] before 1 July. Alternatives include: • Routinator • RPKI-client • Fort • OctoRPKI • Prover It is important to note that continuing to use the RIPE NCC RPKI Validator after 1 July 2021 may lead to security incidents, as we will no longer be making updates to the software. If you have any questions, please get in touch with me. Best regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC [1] https://rpki.readthedocs.io/en/latest/ops/tools.html <https://rpki.readthedocs.io/en/latest/ops/tools.html>

Update on improved rsync repository publication
by Ties de Kock 01 Jun '21

01 Jun '21

Dear colleagues, Over the last weeks, as mentioned in a previous email [0], we have been exploring two approaches to improve our rsync publication process in parallel. The first approach (“batched publication”) changes the RPKI system to atomically publish the complete set of files instead of writing them at multiple places in the code. For rsync, after all files have been written to a new directory, the repository is switched to the new content by atomically updating a symlink. The repository is updated every 15 minutes. We plan to deploy this soon during a scheduled downtime. During this downtime the repositories will be available, but managing a certification authority will not be possible. The second approach uses RRDP as a source of truth and writes the repository to a local disk (instead of to NFS) with krill-sync (which also uses a symlink as the base for the current rsync module). We have an experimental rsync environment based on the second approach available for testing. The environment contains the production RPKI repository. Please note that this environment is experimental and thus is not considered to be a critical service. Do not rely on this service for production networks. We may cause downtime on this service to adjust the configuration. However, when services are available, the content should be valid and contain the same objects as the production RRDP repository. It updates from RRDP every minute. The non-repeatable reads should not occur. rpki2.ripe.net provides all services (rsync repo, HTTPS trust anchor certificate) that rpki.ripe.net provides. The recommended way to test this is by making sure that your traffic that usually goes to rpki.ripe.net arrives at the IPs of rpki2.ripe.net. We will evaluate this environment with multiple relying party instances and a tool that checks for repository divergence over the coming weeks. In parallel, we are finishing the configuration (e.g. metrics and alerting). Please share your feedback with us at rpki(a)ripe.net. We aim to deploy the first approach before the end of the month.

New on RIPE Labs: Future Internet at Terabit Speeds - SCION in P4
by Alun Davies 27 May '21

27 May '21

Dear colleagues, As part of the 2STiC programme, SIDN Labs evaluates and experiments with future Internet architectures. One of these is SCION. In this guest post on RIPE Labs, Joeri de Router and Caspar Schutijser introduce the high-speed SCION router prototype they implemented to find out if a complex protocol such as SCION can run directly on hardware using the flexibility provided by P4. https://labs.ripe.net/author/joeri-de-ruiter/future-internet-at-terabit-spe… Kind regards, Alun Davies RIPE Labs Editor RIPE NCC

New on RIPE Labs: SCION - A Novel Internet Architecture
by Alun Davies 17 May '21

17 May '21

Dear colleagues, At RIPE 81, a group of enthusiastic researchers and practitioners from industry and academia discussed with the RIPE community what role RIRs and LIRs could take on in the SCION next-generation Internet architecture. Ahead of the second SCION BoF taking place today at RIPE 82, David Hausheer looks back at what happened at the last BoF, reports on what has happened since then, and presents what potential RIPE involvement could look like in the future. Read more on RIPE Labs: https://labs.ripe.net/author/hausheer/scion-a-novel-internet-architecture/ Kind regards, Alun Davies RIPE Labs Editor RIPE NCC
