Was Ethereum Classic attacked?
As suggested by the Bitfly mining solution provider, a network reorganization of 3693 blocks occurred at block 10904146.
A diagnostic report was immediately released to explain the identification of the violating miners.
Originally considered a network attack, the event was later dismissed by the team behind ETC.
Another status report released later that day explained that the reorganization wasn't intended, and it happened because miners used old offline software for 12 hours.
So, was it a bug?
