Federico Viticci on Apple's Response:
"Last night, Apple officially acknowledged the issue and explained it was associated with DRM code generation on the App Store. Apple said they had fixed the issue, and Macworld reported that, according to their sources, Apple would also remove all negative reviews that had been left during the hours the bug was spreading on various international App Stores."
I'm actually surprised with the extent Apple has taken to clean up this whole DRM mess.
