The RIPE NCC's statistics now list it as 'available'; reissue not confirmed
The RIPE NCC's statistics show it reserved on 2016-07-17 and available on 2016-07-18. The RIPE NCC keeps reserved IPv6 space next to its allocations for their growth, and the tracker didn't see this range removed from registration, so this is most likely the RIPE NCC returning such space to its pool, not a hold ending. Another change to this range was reported the day before or after (2016-07-19: Added 2001:678:208::/48), so the before-and-after statistics may include it.

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.
