   • You can only unbind an EIP from a CBH instance. To release an EIP, go to the EIP management page and manually release it.
   • It takes about one minute to complete the unsubscription.
   • After you unsubscribe from a CBH instance, you cannot log in to the mapped CBH system and system data cannot be retrieved. Exercise caution when performing this operation.
   • After you unsubscribe from a bastion host, the residual resources will be cleared at 03:00 the next day. If you want to delete a security group, wait until the residual resources are cleared.
