I will tell you that unless something is on fire in my rack, no one from Level3 will even touch anything - and even then they would hit the fire suppression button and leave the room. They do not touch anything in a customer rack. (I have two racks in a local facility owned by Level3).

The contract I signed, had a clause that said if they had to move me somewhere else, they would pay all costs of doing so. I don't know how standard a clause this is.
