TechCrunch drives a bunch of traffic, generally, especially something like Cubeduel that plays well to that crowd. We're somewhat insulated in that many people lack LinkedIn accounts and bounce off the front door.
The first system to fall over was our message-queue that talks to LinkedIn for logins and refreshes. I had to spin up a separate machine at Rackspace just to help logins along. Hopefully that'll hold things steady for a bit.
