1007-1009 Somewhere around there.

Don't ask. Too painful of a story.

There's another duplicate in 91880.

God, a banking system would really have come in handy here...

Not 100% sure, but looked like we lost a block probably due to default jgarzik's pool not retrying re-submiting work when bitcoind was unreachable...

Oh well. Fortunately no one else was mining at that moment. It was a very short round too with just like 500 shares... 

8999X$8.70= $78291 

Yes, exactly 8999 were lost.

kjj, how'd u find the block?

I just clicked back through the chain until I saw a 9000 -> 8999 + 1 transaction around the right date.

You can click all the way back to the genesis block by using the Previous Block links.  Stone Man posted about the loss here on the forums the next day.
