Three hours for a physical problem like this is very little time. Once you discover your equipment is not there, you still have to put it on its place, power up, reconnect al cabling, and check networking. From this kind of mess to a fully functional infrastructure you need at least 12h-16h to function minimally. Probably takes 2-3 days to have that node working as before. When I was on call, I always jocked with my colleages the worst incident you could have in a datatenter was someone swapping two cables.
