I remember reading somewhere that they don't operate at the level of servers; if one dies they leave it in place until they're ready to replace the whole rack. Don't know if that's true now, though.
It does sound like connections do involve water lines though. As they are isolating different water circuits, in theory they could have a dry connection between heat exchanger plates, or one made through thermal paste. It doesn't sound like they're doing that though.
