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>
