(1) Access lines are lines reaching from the customers’ premises to a connection with the public network and
high-speed Internet subscribers are customers that purchase high-speed Internet connection service through
their existing telephone lines, stand-alone telephone lines, or fiber-optic cables. Our methodology for
counting our access lines and high-speed Internet subscribers includes only those lines that we use to
provide services to external customers and excludes lines used solely by us and our affiliates. It also
excludes unbundled loops and includes stand-alone high-speed Internet subscribers. We count lines when
we install the service.
(2) We define a data center as any facility where we market, sell and deliver either colocation services, multi-
tenant managed services, or both. Our data centers are located in North America, Europe and Asia.
