Decades ago an ISP I was colocated at did the same thing. I don't remember the exact details, but it was a DNS server and they either couldn't log in or were relying on the zone files cached in memory or something but for some reason they couldn't power it off. It was already plugged into a UPS, but they had to cut one of the posts off the rack to get the server out without unplugging it, then they plugged that UPS into a bigger UPS on a cart and wheeled it to the new data center they built out in the building next door. The world was much different at the time -- this coloc provider had a good reputation, yet.... they had a keg of beer in the corner of the server room and a stack of adult magazines in the men's room.
