RT @BitMEXResearch
A chainsplit of length two occurred on Bitcoin today. The below diagram shows the miners involved, block timestamps & the time our node's first saw the blocks
* There were no double spends detected
* This was not a consensus issue (All blocks were valid)

@TallTim @emzy a chain of two stale blocks is pretty rare, though, and the "discovered" time stamp (which I think is the time BitMex received the blocks) indicates there may be something weird in the configuration of some of the involved pools.
