‘The audacity met reality': Why Mt. Gox's Bitcoin hard fork died in 17 hours

Need facts to draft breaking alert: who launched the Mt. Gox Bitcoin hard fork, exact launch date/time (UTC), how many blocks/hashpower supported the fork (or % of total hashpower), whether major miners or exchanges signalled support or rejection (names), any token/ticker or chain parameters, and whether the fork was formally abandoned and when. Reply with those details or type 'Draft now' to produce an alert based on the headline alone.
