They might manage to fill the connection limit for apache on each system (I think this is default to 256?).

  This! Apache is the first casualty when attacked by DOS. Default is way lower than 256 I think... You can change that parameter but it kills the optimization.

  It's not very likely that those sites are using Apache on the front lines.

      mpaa.org is using nginx/1.0.5, but the other sites do indeed seem to be Apache servers.
