Normally, that would be the answer. But this time some major miner turned on his cluster just after the difficulty change and ran it about 8 hours and shut it down. If you look at the timestamps at blockexplorer.com it's pretty obvious that blocks were coming in at 12 per hour for about 8 hours then suddenly dropped back to six per hour.
EDIT: It's also obvious that, whoever it was, couldn't manage to quite break 50% of the total network hashing power. It might have been a test (by govco? Who else has that kind of power?) to see if they could still break bitcoin. If so, bitcoin just barely survived.

Some graphs fail when the difficulty change, and take a little while to drop back to normal..
5 days? That was just in the past 18 hours.
okay and now it fell by 4 terahash in the las 12 hrs, something weird is going on here. with the latest 500k heist, im question the practical use of bitcoin, ill stick to the sidelines for now.
5 days? That was just in the past 18 hours.
anyone care to explain how the hash rate nearly doubled in the past 5 days?
