ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2009-03-04 and not issued on 2009-03-06. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

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.
