Looking for office space with Comcast available is not the easiest thing to find. Calls to Comcast Business Class service aren’t always conclusive. As I make calls to listing brokers, they often don’t know if this is available to the building. For small businesses the cost of a T1 line to support high speed uploads and downloads are too expensive. High speed DSL doesn’t provide the speeds that a computer intensive small business needs. So call Comcast and double check, before signing a lease if this is a key element in making your business operate efficiently.
