Interesting - when I tried the "upgrade my library" it did NOT find all the upgradable music. It's only offering to upgrade one of my two Norah Jones albums, for instance - even though both are on iTunes Plus, and both were purchased through ITMS.
The iTunes FAQ is down as well, so I can't look for a solution. Guess I'll have to wait a while until the first wave dies down...
