What the hell is going on with network hashrate?!
http://www.bitcoinwatch.com/Climbed madly to peak at 4.4 Thash ... and now crashed down to 3.2 Thash ... outside statistical variability. Someone or something had a big push and now has backed off ... first attack? Someone trialling FPGAs?
Anyone got the skinny?
That I think is related to the flawed way in which the hash rate is calculated after a difficulty increase. In other words the problem is with bitcoinwatch.com
So just artifact of the averaging ... how boring.
Edit: Would be good if we got some kind of measure for how extreme the variance of the current block generation rate is ...
