Not sure if it's related, but yesterday one of my clients (a top 500 alexa site) suddenly had most search results (when 
googling for things like the site's name) suddenly change to some other shady looking domain that's just sending 302 
redirects to the real site. All the same search results are there, but they're now sending everyone to the wrong domain 
that's just redirecting to the correct place. No idea how Google thought this is correct and I'm totally failing at 
getting anyone's attention at Google to look into this.

This coincided with this message from @google on twitter yesterday:

Heads up: we're pushing a new Panda data refresh that noticeably affects only ~1% of queries worldwide.

But i'm not sure that's related either.
