Pusher has certain soft and hard limits in using its service. Hard limits are automatically enforced by the Service. Soft limits are consumable resources that you agree not to exceed. Though we will sometimes tolerate applications that exceed their soft usages, we reserve the right to disable applications that fail to upgrade once requested to do so.
