AS0 discard ROA - upstream RPKI inconsistency
The only ROA covering this prefix names AS0, which means the issuing RIR has published the prefix as “not routable by any AS” (RFC 6483). If the RIR’s allocation records still point to a live operator, the ROA and the RDAP registration disagree - this is an upstream inconsistency in the issuing RIR’s own publications, not necessarily a hijack.
