Over the last few years, broadband technologies such as DSL, cable modems, and FiOS have become cheaper, faster, and more reliable. The providers of these services now offer "business class" versions, which typically come with some sort of quality of service guarantees, such as minimum bandwidth, uptime, technician response rate, and so on. These "business class" offerings provide static IPs and often even have the option of managed services.
Many companies are considering switching from expensive but traditional technologies such as T1 and T3 lines to the "business class" offerings. But some companies are still doubtful that these services (which were sprung from consumer-grade technologies) can meet their needs.
