2025-02 End of Discussion Phase (Revocation of Persistently Non-functional Delegated RPKI CAs)
by Sebastian Becker 10 Jul '25

10 Jul '25

Dear Routing WG, The discussion phase for proposal 2025-02: "Revocation of Persistently Non-functional Delegated RPKI CAs" ended on 4 July. The proposers have agreed to advance it to the Review Phase. Seven people supported the proposal with some suggesting a more specific definition of the revocation date. However, there was general agreement to trust the RIPE NCC's implementation to address this concern. The RIPE NCC will publish the impact analysis and the policy draft and announce the start of the Review Phase. Kind regards, Sebastian Becker, for the Routing WG Chairs
