Oh I misunderstood, I thought you wanted to do this inhouse. I use <a href="http://www.dyndns.com/" rel="ugc">http://www.dyndns.com/</a>&nbsp;for this stuff. Not as many options as savvis but the price is right if they do what you need. I use them for backup mx for anyone that hosts their own mail server. $20/yr

The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
