Moving RFC 6493 to Historic
status-change-rpki-ghostbusters-record-to-historic-00

The Resource Public Key Infrastructure (RPKI) Ghostbusters Record (RFC 6493)
was published as Proposed Standard in February 2012. Only very few RFC6493-like
records were created in the Global RPKI at some point in time. However, there
are currently no valid RFC6493 records in the Global RPKI. Moreover, there are:

(1) no actively maintained implementations,

(2) no known deployments,

(3) no known deployment plans by Regional Internet Registries (RIRs), and

(4) operational concerns about duplication of functionality (e.g., versus use
of RDAP) and privacy.

The operational experience supports reclassification of RFC 6493 as Historic.
