The RIPE NCC's statistics now list it as 'available'; reissue not confirmed
The RIPE NCC's statistics show it reserved on 2016-05-03 and available on 2016-05-04. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2014-09-03, 609 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

Hold estimate
Estimated hold end 2015-03-02. Possible reissue candidate after this date; not confirmed available.
Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it allocated (dated 2004-02-26) on 2014-09-02 and reserved on 2014-09-03. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed ASNs for 180 days (six months), or longer while still routed, before reissuing them, so the estimated hold end is 2015-03-02. This does not confirm availability.

RDAP lookups
Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
