IT is entirely possible that is was faulty installation, but at the same time why 7000 miles later? Mis-torque? There may be no determining factor until you get into the job.
If the head gasket goes it can pressurize the cooling system, but the radiator itself is usually the weak link.
Why the hose would pop off and be the weak link is odd. That sounds more like a bad installation of the lower hose. The hose pops, you lose coolant, it overheats, the head goes or head gasket goes. Sometimes the coolant is drained by removing the lower hose as it is quicker and easier sometimes. Maybe it didn't get put back on well enough.
