Notes and record state
Record note
COSS was taken offline on 2020-01-07 and later described acquisition negotiations and a relaunch plan. Because the record is too ambiguous for a clean dead-side classification, it is moved to inactive pending deeper verification.
Revision state
Records may be incomplete, approximate, contested, or revised as better evidence becomes available.
This record may be incomplete or revised. Dead-side entries prefer archived URLs over original domains. Dates, causes, and classifications may change when stronger evidence becomes available. Contact / corrections
