Presumably the costs for a platform are passed on to the platform's customers from that platform's cloud provider (with profit). When a spike happens due to, say, a DDOS, does the platform first have to negotiate with the cloud provider to waive the cost? Presumably the costs for a cloud provider are passed on to the cloud provider's customers from that cloud provider's operating costs (with profit). When a spike happens due to, say, a DDOS, does the cloud provider first have to negotiate with its downstream suppliers (e.g., energy, network peering, etc.) to waive the cost? ...
