The crisis has been dubbed by Zune users 'Z2K9', due to the apparently synchronized faceplantings across the country. According to tipster Michael, the Zune users experienced something like this:
Apparently, around 2:00 AM today, the Zune models either reset, or were already off. Upon when turning on, the thing loads up and... freezes with a full loading bar (as pictured above). I thought my brother was the only one with it, but then it happened to my Zune. Then I checked out the forums and it seems everyone with a 30GB HDD model has had this happen to them
This report is consistently corroborated by literally hundreds of others across the various Zune support and fan forums. [...]
Here's Microsoft's official response for the time being (it's clear they just woke up and probably haven't even flipped on their coffee pots yet):
We are aware that customers with the Zune 30GB are experiencing issues with their Zune device. We are actively working now to isolate the issue and develop a solution to address it. We will keep customers informed on next steps via the support page on zune.net
