My colleagues and I at Virginia Tech, IIJ, RIPE NCC, and MANRS have developed a new measurement platform (https://rovista.netsecurelab.org/) to measure the current deployment status of ROV.
For cross-validation, we've been trying our best to collect some "ground-truth" datasets manually from rpki.exposed, personal communication, and official blog posts from network operators, but it is a bit hard to scale. It would be really appreciated if we can directly hear RPKI validation status from network operators by participating in this survey!
