The service will attempt to be available at all times except for limited periods for maintenance and repair. However the Service may be subject to unavailability for a variety of factors beyond our control including emergencies, third party service failures, transmission, equipment or network problems or limitations, interference, signal strength, and may be interrupted, refused, limited or curtailed. We are not responsible for data, messages or pages lost, not delivered, delayed or misdirected because of interruptions or performance issues with the Service or communications services or networks (e.g., T-1 lines or the Internet).
