Maaven posted a short time ago that the 3.0.8 Public Test Realm (PTR) servers are being taken offline for an update tonight. There is no ETA when the PTRs will be back up.
There was a recent update to the PTR patch notes, and there has been a lot of activity on the PTR forums from the blues. It should be noted that Ghostcrawler once again today reiterated that dual spec will not be unveiled in 3.0.8.
There's a few of us here that will be up tonight, so check back and see what the new build brings. I'm placing my gold on more clam updates.
