Are there service-related problems with DSL? Is it available everywhere?

Most of the problems that plagued DSL in its early days have been resolved. Nationwide, some customers report difficulties in transitioning to DSL, and with some of the larger companies, it can take a surprisingly long time to get DSL installed. But most community based telecom providers like DTC have not had similar installation problems or delays.
DSL service is now available across most of the U.S., but it’s still not offered everywhere. In addition, DSL technology still depends on network quality and is distance-sensitive. While the technology has improved significantly since DSL was first deployed, its availability is still tied to the status of the provider’s network equipment and the physical location of the customer; i.e., how close a customer is to the equipment that connects homes and business in that area to the provider’s central office.
Once service is installed, some customers notice the speed varies and is slower-than-expected on occasion. The fact is, no matter how much bandwidth is available, your connection will only be as "fast as the weakest link". If you are viewing a website in California and there is a piece of equipment having trouble somewhere in between, your speed will be affected. DTC provides all customers up to the requested amount of bandwidth within our network, but we remind you that actual transmission speeds vary.
True to our service tradition, we strive to offer DSL that’s as reliable and dependable as our voice service. We’re confident that, compared with standard dial-up access, our DSL connection will be an important value-added service for the homes and businesses in our service area.
