The leap in difficulty must mean all the 500-600Ghash/sec 28nm ASICs are coming online.
I would imagine they burn in test for 24 hours but with so many units to build they would have to rotate them out.
Soon a $5000 machine like that will only make a quarter coin per day.
I'm glad that you're not an ASIC supplier, because that's fraudulent and dishonest.

The corruption explained there matched the pattern seen in representative cases supplied by the core team.
The core team may not have yet awarded the bounty, and there were a few other possibly contributing factors regarding proper use of LevelDB on OSX before the above work... but there's certainly a strong case made that a real fix has been discovered and deployed.
