Because of variations in the telephone company wiring infrastructure, Covad Communications cannot guarantee that a particular service or speed will be available to you until we actually complete the service set-up, even if we believe that it should be available and accept an order for it. All orders are subject to downgrade or cancellation as a result of unforeseen problems with the wiring infrastructure. However, statistically, the vast majority of the orders we accept are successfully installed at the speed offered when the order was received, and we are constantly refining our ordering tools to further improve their accuracy.
