## AI overview

RPKI fail-open behavior protects reachability, but an upstream break can quietly change routes from Valid to NotFound without alerting operators. The article traces the chain from CA account through repository, validator, RTR session, and router policy, citing credential compromise, missing or deleted ROAs, validator crashes, and router policy inconsistencies. It presents RAVEN's `raven rtr monitor` as an independent RTR client that tracks cache payload changes and sync timing against an adaptive baseline, distinguishes full resyncs from incremental updates, and streams route validation changes. The tool can surface unusual VRP movement and route transitions, but it does not yet detect a cache that answers while its serial stops advancing, alert on RPKI-driven changes, compare caches, inspect router policy, or repair problems. It supports TCP and TLS, not RTR over SSH.

## Source excerpt

ROV turned your validator into a forwarding policy source. The registries have strengthened their side of the RPKI, but the chain from repository to router runs on your infrastructure. When that chain breaks, it often breaks silently.
